Extension only shows blank box after updating to Chrome 78

[richardeid]

After updating to Chrome 78 when I click on the extension button to pull a video out to PiP all I see is a blank box that I can't interact with or move. The source video stops showing but the audio keeps playing. The only way to back out at that point is to click the extension button again and the video begins showing on the original page again.

The problem started with Chrome 78.3904.70 and continues with 78.3904.87.

[XuRulin]

I also encountered this problem

[derN3rd]

Think this is a bug with Chrome 78, not with this extension, as it also happens when using the native api or js snippet to toggle PIP. This was already reported in the chromium bugtracker: https://bugs.chromium.org/p/chromium/issues/detail?id=1018513&q=pip&colspec=ID%20Pri%20M%20Stars%20ReleaseBlock%20Component%20Status%20Owner%20Summary%20OS%20Modified

Quickfix: enable flash on youtube/the site where you see this white PIP window

[beaufortfrancois]

I wonder if that could be related to SkiaRenderer finch trial. Can you folks disable flag at chrome://flags/#enable-skia-renderer and let us know if that fixes your issue?

[richardeid]

Quick update. I enabled flash on a couple different sites but that didn't change the outcome. Still just a blank PiP window.

Also, I disabled that flag, restarted and still had a blank PiP. And I tried also again allowing Flash while this flag was disabled and no change.

[derN3rd]

Even with disabled flag, white screen in the PIP window. Allowing flash in the site settings works for m tho

EDIT: nevermind, after trying out with that flag I can't get it to work (even with the flash settings)...

[richardeid]

Was just updated to Chrome 3904.97 that resolved the issue for me.

[derN3rd]

Just tried to update to 78.0.3904.97 on my ubuntu, but the issue still occurs. On Twitch/Youtube I found out that starting a video in lowest resolution (160p on Twitch, 240p on Youtube) opens the correct PiP and changing to higher res than works. So I'm using as a temporary workaround

[beaufortfrancois]

Can you folks still reproduce this issue with latest Chrome stable?

[richardeid]

Weird. This was definitely fixed for me after 3904.97 but I hadn't used it in about a week now and it appears to be broken again. I can reproduce it both by using the extensions button in the toolbar as well as double right-clicking on Youtube and using the menu option from there.

[derN3rd]

Still broken for me on my Linux 78.0.3904.108 (Official Build) (64-bit)

[derN3rd]

I enabled the debug log (https://pastebin.com/UKwab69W) and found something that looks interesting: WARNING:x11_util.cc(1399)] X error received: serial 3840, error_code 3 (BadWindow), request_code 4, minor_code 0 (Unknown)

I had Youtube open on a video. The first line, is the first log after opening PiP (which was a white screen). At line 223 I switched to 240p, which showed the PiP video. After that I switched to 1080p again, and the video was visible from that on.

About my setup. I'm using Ubuntu 18.04 (and 16.04, both have the same behavior), with i3 as desktop manager.

[richardeid]

Interesting. I am on a different PC right now. Still using the latest version of Chrome and the extension as far as I know. And it appears to be working on this machine. As far as I remember this setup of Chrome is mirrored on each machine as I'm logged in to the same Google account in Chrome. I'm not sure what would be different between the two but if anything comes to mind I can check.

[inothilmi]

There is still no improvement in this issue? looks at a black screen.

[ghost]

Works fine if you use the LOWEST possible quality setting (<= 200p on Youtube / <= 160p on Twitch) You DO Need the addon for twitch, unless you use FrankerFaceZ.

[richardeid]

On some sites, such as AT&T TV NOW, there is not a quality selection so there is no way to resolve this issue using that method.

[chiumax]

I'm on Version 79.0.3945.79 on both my PC and my laptop. PC not working even with the quality workaround people are using. Laptop works fine and great. I wonder if it has something to do with my dual-monitor setup

[chiumax]

I have gotten it to work with no problems on a different chrome user - with only this extension installed.

[beaufortfrancois]

Oh really!? Can you re-add your other extensions one by one and see when you can reproduce the original issue?

[chiumax]

Okay, I'm not sure what the problem is. Initially, I thought it was the extensions causing the problem. So on my original account i disabled and removed every single extension, restarted my PC.

I added it back and it still didn't work. Maybe it was because I had multiple windows of chrome open. I merged everything under one window - still didn't work.

Now, I went back on youtube to find the original video I played to make it work on the fresh alt account - it works. But it only seems to work with that video.

[derN3rd]

Just found out, when I disable floating on PiP window with my i3 hotkey, that it shows the video. If I then switch it back to floating it still works. So it might be because of the initial forcing to be a floating window. Will dig into this and test some things out with my i3.conf

[chiumax]

I've done some more testing and this probably sounds crazy.

This is what worked for me to get it to work in the same tab:

This has to happen in the same tab Go to: https://www.youtube.com/watch?v=1nnRC6jDOCI

Open it in PiP, then close it, then on the same tab navigate to any yt video you want, you can even paste the link in.

I think maybe it has something to do with that yt video being vertical or something.

[chiumax]

I'm more curious why it works normally on my laptop but not my PC. Even with different accounts. I disabled my second monitor so it isn't the dual monitor setup that's causing issues. I might go ahead and re install chrome

[chiumax]

I have tried:

• different chrome profiles
• uninstalling all extensions
• reinstalling chrome
• single monitor setup
• single window setup (all tabs on one window)
• changing resolution

None of them work except going to : https://www.youtube.com/watch?v=1nnRC6jDOCI on the same tab.

I am convinced that it either has something to do with the fact that the video is vertical/different resolution but for some reason changing resolution on normal videos doesn't fix anything for me. Or my monitor resolution

[chiumax]

I took a look at my laptop's screen resolution, 1920x1080, and saw that my scaling was 125%.

Changing it on my PC (it was already 1920 x 1080 but 100% scaling) made it work for tabs that already had youtube on them. But the extension doesn't work if I open new tabs with youtube.

Changing it back to 100% scaling also made the tabs that already had youtube on them work. So I'm seeing that whenever I mess with my display, tabs with youtube on them will work.

What doesn't make sense to me is that my laptop can stay on 125% scaling and not have any problems with new tabs or windows with youtube on them. I'm still trying to figure out why.

[beaufortfrancois]

I wonder if you're experiencing some side effects from "calculate-native-win-occlusion" experiment. Please disable flag named "calculate-native-win-occlusion" in about:flags, restart Chrome, and let me know if that changes anything for you.

[chiumax]

Hmm, doesn't seem to be changing anything @beaufortfrancois

[beaufortfrancois]

Argh :( Noted. How about resetting Chrome’s field trial configuration using chrome.exe --reset-variation-state to see if the issue disappears?

[chiumax]

No, I exited chrome before I did chrome.exe --reset-variation-state and the issue still persists. However, for the time being I am completely ok with changing scale to 125% and back to 100% to get it to work for existing tabs with video.

[beaufortfrancois]

If people are still experiencing this issue, I'd love if you could share JavaScript result when running the script below. Here's how to do this:

1. Go to the website where you're having issue with Picture-in-Picture
2. Open JavaScript console by pressing Command+Option+J (Mac) or Control+Shift+J (Windows, Linux, Chrome OS) to jump straight into the Console panel.
3. Copy/paste code below and execute it by pressing Enter.

var videos = Array.from(document.querySelectorAll("video"))
  .filter(video => video.readyState != 0)
  .filter(video => video.disablePictureInPicture == false)
  .sort((v1, v2) => {
    const v1Rect = v1.getClientRects()[0];
    const v2Rect = v2.getClientRects()[0];
    return v2Rect.width * v2Rect.height - v1Rect.width * v1Rect.height;
  });
videos.forEach(video => console.log(video));

4. Share result. See screenshot below

Before launching PIP

After launching PIP

Chrome Version 79.0.3945.130 (Official Build) (64-bit)

[beaufortfrancois]

Do you see any improvements when resizing the PiP window, or when toggling play/pause from the YouTube player?

[derN3rd]

No. But closing the PiP window and reopening fixes it.

I still see the same messages as in https://github.com/GoogleChromeLabs/picture-in-picture-chrome-extension/issues/34#issuecomment-557172899

[beaufortfrancois]

Can you reproduce with another window manager?

[derN3rd]

Works fine when I switch to Gnome (Ubuntu 18.04 bionic), only broken on i3

[richardeid]

I get this same result if I go to YouTube as well. Am I doing something incorrectly?

[beaufortfrancois]

@richardeid Can you share YouTube screenshot as well? I wonder if "AT&T TV NOW" is intentionally blocking PiP.

Can you execute this new bit of code and let me know what it logs?

var videos = Array.from(document.querySelectorAll("video"));
videos.forEach(video => console.log(video, video.disablePictureInPicture));

[richardeid]

This is with the new code:

I've done PiP on ATT before and only started having a problem when everyone else did...but only on this machine. I have another computer at work that I can PiP just fine with from any site. And that's without having to do the YouTube 240p trick or resizing boxes or anything.

Anyway, here's YouTube:

And on this machine I can get YT to PiP if I set the resolution to 240p first then back to 1080p. Here's what it shows when I do that:

I must be doing something wrong.

[beaufortfrancois]

Can you make sure you select "x message", instead of "No verbose" so that I can see logs for all screenshots you've sent?

[richardeid]

OK yeah that was it. Sorry. Here's an updated shot:

[beaufortfrancois]

I wonder if a video from another context went to PiP... Can you execute same javascript code in all frames? Basically, select "top", then execute code, select second option, then execute code, and so on until the end. I think you can omit options that are extensions.

[richardeid]

[beaufortfrancois]

Can you reproduce the PiP issue when clicking "Toggle Picture-in-Picture" button in https://googlechrome.github.io/samples/picture-in-picture/? I'd like to know if it's a PiP issue or a website issue?

[richardeid]

Yeah, same thing. And also I clicked the three dots on the player and clicked PiP from there and same thing.

One other detail I forgot. The first time I click PiP I get just a transparent window with nothing happening in it, unable to be resized or moved. If I toggle off PiP and then back on after that, the PiP window is solid black, but still unresizeable and unmovable. If I toggle off PiP and back on again at that point it's always a solid black PiP window. If I close the tab and reload the page in a new tab I'll get the transparent box again before getting the black box. Not sure if that detail matters.

edit: Ooh, yeah. Sorry. I test all this stuff out in regular and Incognito when I troubleshoot, so don't worry about seeing uBlock up there in my extensions. I test without it and the result is the same.

[beaufortfrancois]

Do you have any flags that may conflict? In about:flags internal page, click "Reset all to default" button, and give it a try again.

Thanks for the details!

[richardeid]

I'm not sure if I had any flags changed. I play sometimes. Anyway I reset it and restarted Chrome and no change.

[beaufortfrancois]

Can you share log messages in about:gpu before and after your enter PiP? (we'll get there... sorry ;) )

[richardeid]

Don't be sorry. Bugs, man.

And if you need me to paste it I will, but I ran a compare on the before and after output in Notepad++ and the only difference it showed was the time the data was exported.

Thanks. Let's continue investigating then as I don't see anything yet.

Can you go to the internal page chrome://media-internals/, look for the video player of https://googlechrome.github.io/samples/picture-in-picture/, and share logs as well?

Argh... I'm starting to run out of ideas to figure out what is happening... I'll ask friends around and will come back to you.
