Comment 1 Nate Graham 2024-01-17 00:26:03 UTC 
Does it happen on X11? If not I strongly suspect this is a bug in GTK3's Wayland support.

Comment 3 Nate Graham 2024-01-26 22:14:33 UTC 
Thanks. Cannot reproduce on Wayland with Quod Libet.
Comment 4 Nate Graham 2025-02-18 15:35:21 UTC 
Can reproduce with Deluge and Quod Libet today. There are other glitches too, such as arrows appearing in the center of the window. I suspect those arrows are implemented as a new top-level window, and that's what's confusing the Task Manager into thinking it's a multi-window app — because at that moment in time, technically it is!

Probably the GTK devs never noticed this because on GNOME, there's no always-visible panel or dock that would expose the issue.

Please report it upstream to GTK. Thanks!
