So im on zorin so basically ubuntu with gnome. Anyway I see this thing and it only happens with firefox but the switching between various windows I get back to firefox and it will be full screen size but not actually full screened so now I can see another window peeping over the top. Does not happen consistantly at all but like a minimum of once a day I notice it and click the window back to small and then full screen again to get it to use the whole real estate. Just seeing if anyone has seen behaviour like this or better yet knows something about it.
I think I have seen a similar issue. Mine is that sometimes my firefox gets stuck in the background and I can click the icon in my dock to maximize it. Nothing happens. I have to hit the Windows key to view all my windows in that particular workspace, then click firefox to get it to the front. Sometimes it doesn’t work and I have to close out Firefox and reopen. Is that similar to what you’re seeing ?
actually that sounds way worse. I never have to close it out and I can always get to it. It just sorta looses its fullscreenness while in fullscreen. Its very odd.
