Could be an upstream bug since it also happens with :

• [BUG] Doesn't display on top of full screen windows, or maximized window without panel icedman/search-light#77
• [BUG] Doesn't display on top of full screen windows, or maximized window without panel oae/gnome-shell-pano#263

But i can't say what exactly the bug is, so it can help if you guys can figure out and report if it is upstream

Consider installing the Disable unredirect fullscreen windows extension, which toggles the compositor setting that bypasses the compositor for fullscreen windows.

[RushingAlien]

That's a pretty temporary solution, consider looking into gnome's notification and alt+f2 shell menu, looking glass too, they all work on full screen windows.

But for now ig I'll enable that the disabel direct scanout extension when i use this extension, thanks

Unfortunately, I'm unable to reproduce this issue on any of my systems.

[RushingAlien]

are you on x11 or wayland?

[G-dH]

Both. However, it seems that using Meta.disable_unredirect_for_display() when the thumbnail is on the screen should be the correct solution.

[G-dH]

Just a note for others: Meta.disable_unredirect_for_display(global.display) calls are being stacked, and each Meta.enable_unredirect_for_display(global.display) call works against the top of the stack. Therefore, a single Meta.disable_unredirect_for_display(global.display) call can globally disable unredirection, although GNOME Shell manages the enable and disable state for modal dialogs and animations. So it is important to not call disable repeatedly if you want to restore its original state on extension disable.

Can confirm that it works. :D
Thank you

Hey, just letting folks know, that once this merge request that allows direct scanout(unredirect) on non-fullscreen clients, this may not need to be done anymore.
