v4.0.0 UI lag

[meow81]

Since updating to v4.0.0, I'm experiencing a lot of lag with the UI catching up with the mouse cursor position and selectable elements of UI like play buttons when hovering over an album cover not showing or very delayed, volume slider delayed appearance, and menu items highlighted background color that shows when you are hovering over it very delayed.

The product unfortunately feels broken in this version. Should I try a reinstall? Let me know what additional info I can provide.

see the video for detail and pay attention to the mouse cursor: https://youtu.be/HfmpdkQb82o

forgot to show proof of the version in the video, but took a screen shot afterwards:

My system info: Windows 10.0.14393 x64 Processor AMD FX-8370 Eight-Core Processor, 4000 Mhz, 4 Core(s), 8 Logical Processor(s) 8.00 GB RAM NVIDIA GeForce GTX 950

where is this in the FAQs? I looked, but it's not listed on that page.

If appropriate please attach the DEBUG information zip file that you can generate by following the instructions in the FAQ

@MarshallOfSound that last CPU Profile looks like the majority usage is with jQuery, or am I reading it wrong?

[MarshallOfSound]

@jostrander Yeah, that one appears to be mainly jQuery but it is within normal usage bounds. If you turn off "scroll lyrics automatically" in settings that usage will drop to 0.

[VenomXII]

after turning off that setting, do i need to restart the app?

[MarshallOfSound]

Nope, the jQuery animation will stop immediately

[VenomXII]

lag still exists :(

[jostrander]

Can you take another CPU profile without that enabled?

[VenomXII]

Here you go, i put it through its paces during this, lag was everywhere got my cursor doin the jitter thing again. CPU-20161024T235051.zip

[MarshallOfSound]

@VenomXII Are you sure the DEV_MODE improves the situation?

[VenomXII]

not really, its not much of improvement other than it lets me use my cursor while the program is minimized. if its in normal mode even when minimized or in the background my pc gets brought to a crawl.

[MarshallOfSound]

@VenomXII In task manager can you screen shot which process is using the CPU. Also screenshot the helper processes

[VenomXII]

If i force close the program and reopen it, it brings everything to a crawl/stop, then it comes back, its still in dev mode when i took these screenies.

[MarshallOfSound]

@VenomXII Out of interest and a completely wild guess, can you install Bonjour Print Services. Restart your computer, and see what happens 👍

[ericralph]

It does look like GPMDP is indeed using a massive amount of CPU, albeit variably. Moments after opening (no music playing, haven't even opened the interface), it jumped to 100% CPU utilization and is hovering around 25-75% currently.

[Dogodile]

@MarshallOfSound Installing Bonjour Print Services and restarting resolved the issue here. I guess I never had it installed on my Surface but did on my desktop. Edit: My fix by restarting was short lived, laggyness is back. For now it seems rolling back is the best fix for me.

[VenomXII]

@MarshallOfSound I'd rather avoid installing anything apple related on my windows machine. and per @Dogodile it seemed to not work.

[jostrander]

@VenomXII I don't know if you read the same thing I did, but he said it resolved the issue. The bonjour print services are for chromecast and is a standard that Google decided to use.

And I didn't see the edit because I read this via email. My bad, but either way its for chromecast, even if its apple related.

[MarshallOfSound]

To stop the "I have this issue as well" spam I'm going to lock this conversation.

This will hopefully be fixed by Electron 1.5.0 and a Chromium version bump. As soon as I get my hands on a build for that version of Electron I'll link a build up here for you guys to test out.

If anyone has any magical insights on the cause or possible solutions for this issue please raise them in Gitter

I'll keep exploring possible causes and hopefully we'll get this fixed

[MarshallOfSound]

I have reports that 4.0.2 fixes this issue. Can you guys please test and confirm 👍

[lucaseverett]

No change for me. I also deleted the "AppData\Roaming\Google Play Music Desktop Player" folder just to be safe.

I also did a clean install of Windows 10 and tried a different video card last week and there was no difference.

[lucaseverett]

Is there a way to force 3.6 to not update? I've been reinstalling 3.6 often because even though I don't manually update it eventually it updates by itself.

[MiguelCTorres]

Still bugged for me :( I deleted the Roaming GPMDP folder too. I can start music, but I cannot touch anything after press play button.

[donewert]

Yes. It is still flashing for me on MacBook Pro. However, it only seems to happen when on the laptop (retina) monitor. If I use an external monitor (HDMI/1080P) there don't seem to be any glitches at all.

The glitch I am seeing (again, only on the retina screen) is best described as a flash (turns white for a split second) in the screen right after the each background artist image is loaded. Just distracting is all. My Parallels Windows 10 VM works great.

Maybe another clue is on my Dell XPS 13 with a quad hd touch display, I see glitchy issues as well (mouse roll-over flashing). Maybe has something to do with ultra HD rez monitors?

Thank you!

[meow81]

That's interesting, I'm using a 4k monitor with Windows recommended scaling of 150% turned on. Not sure if that helps. @MarshallOfSound, offer still on the table to do TeamViewer if you think that will help with troubleshooting.

[lucaseverett]

I also have a 4k monitor. As a test, I turned off display scaling and set it to 100% and all of the glitches go away. So this does appear to be an issue with scaling. Anything above a 1.0 scale factor glitches to the point of being unusable. With 3.6 it works at all scale factors.

[meow81]

Good find @lucaseverett . I would expect it to work with scaling and hope the fix is prioritized (if it is related to that). Without scaling on 4k, some apps look awful or are really tiny, almost unusable.

[EricPutney]

1080p display here, changing scaling from 150% to 100% and signing out/in solved the problem completely for me!

[ericralph]

I also have display scaling set to 200% (Surface Pro 4 is nearly nonfunctional without scaling). I can also verify that installing the Bonjour Services did nothing noticeable to alleviate the problems I've been having.

Raised https://github.com/electron/electron/issues/7882

Can you guys with the DPI issue test this build. https://mega.nz/#!eNdDBDCa!rPhFnzwTc5q3Soz8bkdBnmUNsLT6-Y3t4nuI4mkuJkY

[donewert]

Works the same here. Just tried it with no scaling, looks perfect. As soon as I scale to 150% the issue is back.

[MarshallOfSound]

Here is another one 😆 This one theoretically should work 👍

https://mega.nz/#!KM0izAra!cAUickZUiQEdMJy7XiDMFB7mPNOUAtE6aOkqPC7G9q8

[donewert]

Seems to have done the trick! Works great in Windows at 150% scaling. I look forward to trying it out on Mac.

Thank you!

[MarshallOfSound]

@donewert Although that one works it is not a fix. It is simply determining the exact version number in Electron that the issue started occurring. You're welcome to use it 😆 but it isn't fixed yet 😆

[donewert]

Ah, gotcha. I will enjoy this special version on my PC then. :)

[ericralph]

I can verify that that modified build from the MEGA link works MUCH better. Still not exactly snappy, but it is very functional.

[lucaseverett]

The mouse hover issues are gone in that build but the frame rate is still very low.

[BalzGuenat]

I have a 4K screen and the same issue. The build you just posted fixes the hover spasing but the minimize, maximize and close window buttons for the window stopped working. Framerate seems low (feeling <20). Pulling the window to the top edge to maximize still works. This is on Windows 10.

[MarshallOfSound]

Guys, please no one download and use that build. It was a hack job with badly compiled dependencies and some missing ones. It was PURELY FOR TESTING PURPOSES ❤️

If you want to revert to 3.6 and not get bugged by update notifications just change your hosts file to point update.gpmdp.xyz somewhere else temporarily. (This is not recommended as you won't get the potentially fixing future update)

I'm going to lock this up again to prevent spam. I'm hoping that the next Chromium bump will fix this for you guys. Stay tuned

[MarshallOfSound]

OK guys, new theory to test out, can you guys try this build ASAP and let me know if it works.

https://mega.nz/#!jRNyzDIB!dAAEyDCwUrwed2q-7RubOwwqxzhg3xSb6lOqxkx4I2c

EDIT: Bad build 😢

[boulund]

Sorry to say, it doesn't work well at all. Interface is laggy, mouse-over effects jump around all over the place.

[MarshallOfSound]

@boulund Can you try launching the .exe file from CMD like so.

"Google Play Music Desktop Player.exe" --enable-use-zoom-for-dfs=false -- --enable-use-zoom-for-dfs=false

EDIT: Uploading a new build now, I totally screwed up the other one

[MarshallOfSound]

https://mega.nz/#!WUkDSSya!PSuPahIn3CF8DIqA9XuqTlgLdysbo_PwJ8cg6bNLVkg

[boulund]

No mouse jitters! Performance is also good when not maximized. Still rather sluggish when maximized on my second monitor (2560x1440), but that might be because of my machine being a laptop with a weaker processor...

[MarshallOfSound]

@boulund Sweet, good to hear that I finally tracked it down 😆

Fix should go out next release 👍 Until then feel free to use that build I just uploaded 😄

[boulund]

So, what was the cause?

Edit: nvm, see it now! :)

[MarshallOfSound]

@boulund Chromium 53 changed the way they handle display scaling on renderer windows. They automatically enabled the enable-use-zoom-for-dsf flag which apparently doesn't cope with webviews very well. Forcing that flag off fixed the issue 👍

See the commit I just pushed for reference.

[ericralph]

At least for me, the 11/10 build was much worse than the previous one. Very, very laggy and could not even get the hover interaction aspects to work at all.

[wcomartin]

anyway to make a MacOS Siera version of this build or is this going into the mainline soon?

[donewert]

I just upgraded to the latest (4.0.3) on Sierra. The problems persist there. Would be happy to test any builds if needed.

[wcomartin]

the latest build actually seems worse than 4.0.2, i cant even see the queue or the left nav anymore.

edit: works fine on my 1080p monitor, but the Macbook Pro Retina screen is a no go
