I don’t know where to report a bug specifically caused by GNOME Wayland support or Firefox. I’m missing that feature a lot; it worked in Xorg.

My distro is CachyOS. When I open Picture-in-Picture mode and switch to another app the video hides. For instance, I want to play a game and watch a video, but I can’t because it disappears.

Here’s a recording of the issue. I don’t want to deal with uploading it to my own server, so I uploaded it on Discord: Video Link.

Firefox’s picture-in-picture mode is a detached window so unless you toggle “Always on Top” on the detached window, the playing video will be obscured by the main Firefox window if you focus that. Is that your issue?

If not can you clarify the issue?

I never use Xorg so don’t know different than that Firefox’s picture-in-picture window doesn’t stay on top by itself.

Well, Firefox can, on X11, decide if a window should always be on top, so it does it for its picture-in-picture window.
On Wayland though, due to its security model, an app cannot decide this on its own.

If you right click the picture in picture window, you should be able to select the “Always on Top” toggle for it.

That’s the workaround for now. The proper solution would be an proper protocol for picture in picture, similar to those under iOS or Android. But while they are discussed, it probably will still take some time.

thank you it helped but still i think its bad for user who switched from windows to linux and he depend on it and then thinks linux cant do it

as codedOre said i set alway on top it works but its annoying do it because you always when close it must do again else it will hide as on video

There’s a Gnome Extension that automatically makes PiP show on top. There’s also an additional option to make it show on every workspace.
