8 months ago I think you may have (accidentally?) enabled the advanced setting "Sync video with ambient light". This draws buffered video frames on top of the video, which causes Firefox's pip button to disappear.
This has always worked this way.

Sync video with ambient light is not enabled

8 months ago That's strange, does it still appear/disappear after you disable the ambient light and then pause/play the video?

Disabling Ambient light does indeed fix the button, but it stops working when I re-eanble it. I made a short video clip to see it working in action, I use the hotkey "A" to disable and re-enable Ambient light to show the buttons behavior.

8 months ago Maybe there is a conflict between multiple addons. What other addons are you using? And does it still happen when you disable the other addons?
And what are those Tab and Mousemove icons at the bottom of your screenrecording?

Disabled ALL other extensions, still the same.
The TAB and mouse icons are in the video, ignore them (it's a video game clip, it's part of the UI of the video game).

8 months ago Then my addon is overlaying something on top of the playing video, but I have idea what it could be. You could check that via these steps below. Could you make a screenrecording of these steps?:
<video ... > tag, but it is probably highlighting another tag on your pc.(You could follow these same steps with a paused video to detect any differences)
But, in case there was no other element there must be something different between our devices:

8 months ago I'm also on the same Windows and Firefox version, created a new profile, but still do not run into the same issue. So I think we might be dealing with a Firefox bug specific to your hardware. That seems to be the only difference left. We might need to go into Firefox debugging territorium and find out what feature of Firefox is causing this bug.
You could uncheck some of these 4 css properties in the panel in the middle (Make sure to select the <video ... > tag as in stap 5). Maybe one of them is the cause.
They are also applied when the video is paused, so I doubt it. But who knows at this stage 😄
Another thing you can try is deleting the <div class="ambientlight"> tag in the left panel. (Click on the tag, then press the Delete key on your keyboard.)
If that works revert the deletion (Ctrl + Z with keyboard focus on the left panel) and try to delete the deepest tag that fixes the issue.

8 months ago Unchecking any of those css properties does nothing.
Deleting anything inside <div class="ambientlight"> fixes the button but disables ambient light.
At this point, it's a minor inconvenience, I don't think it's worth digging into further since it seems to be something on my end. The only thing I can try is maybe install Firefox 123 since the problem only started after version 124.

8 months ago Aha, then I'm sure it's a bug in Firefox 124. Probably some z-index fighting between the ambient light canvas and the video. You can report it to Mozilla so that they can take a look and fix it in a next version.

Never mind, just tried version 123 with a clean profile, and it's still the same. GPU divers maybe? Some setting in the drivers maybe? I don't know. I give up :P

8 months ago Could be. Maybe it's caused by the hardware overlays Firefox has recently enabled to support NVidia's video super resolution feature?
You can disable the hardware overlays in the about:config by disabling these flags:
gfx.webrender.dcomp-video-hw-overlay-win-force-enabled
gfx.webrender.dcomp-video-sw-overlay-win-force-enabledThose settings were already disabled, changing them to enabled did nothing. I also disabled AMD's video super resolution from the driver just in case, still nothing.

8 months ago Then I'm out of ideas and will also give up.
The last step you could take is to report it to the Mozilla developers.

7 months ago Just an update, the issue got magically fixed. I suspect it's Firefox 125.0.2, although there is nothing in the release notes which could be related. So.... ¯ \ (ツ) / ¯
Bug description
The Picture-in-Picture button in the latest version of Firefox (v124.x) is invisible while the video is playing. The button is still there, because the mouse changes when hovering over the exact location. The button does appear when the video is paused.
Steps to reproduce the behavior
Browser
Firefox
Operating system
Windows
Extension version
2.38.1
The bug still happens in these conditions
Additional context and/or screenshots
I believe the bug started to happen with Firefox update 124.
