Mini dialogues like add node sometimes disappear and either have to be re-opened or refuse to float to the top. The following logs support this:

gnome-shell[1454] Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0xe00004
gnome-shell[1454] Invalid WM_TRANSIENT_FOR window 0x0 specified for 0xe00325.

Steps to reproduce

1. Create a scene
2. Open the new node dialogue with ctrl + A
3. Exit this and retry step 2 until this happens (does not happen all the time, mostly fine after a restart for a little while)

Minimal reproduction project

This is project-agnostic, happens on any project (including godot examples). I understand how little this issue provides in repro steps but it's worth a try.

If you mean - window just "hide" and you can not alt-tab on it but you see it on Gnome overview - same happening to me on Wayland with Godot 4 - very randomly and very annoying.

Open the new node dialogue with ctrl + A
Exit this and retry step 2 until this happens

from my experience with this Editor behavior - it happening only when you select "text field" on creating new window or even opening GDScript/Shader editor

there is way to restore window, without closing editor - you need to "switch focus" from text-field element to any else, and you have 1 frame to do it - on alt-tab to this "hidden-bugged window" it show itself for 1 frame - and if you click on some other UI element for this 1 frame - bug gone and you can again use this window.

My current solution - Editor -> Editor Settings -> Interface-Editor-> check Single Window mode - setting this solve this behavior for me.

P.S. im not debugging this bug and not bugreporting for reason - this bug is way too random/inconsistent and idk if it Godot or Wayland bug or x11-wayland layer because Godot use x11... too much to debug

Yes that's it, it didn't happen all too often but happens a lot more, but that was also before updating to 4.1.

Side note, wayland is just the protocol so you can't have a wayland bug persay, in my case it would be a mutter bug, but whatever window manager you use. If you use a different window manager then it's either xwayland or godot itself.

Waiting until the #57025 got merged has a meaning for this issue, I guess.

I'm pretty sure that this is an XWayland issue, since we only have an X11 backend for now.

Thanks for the report! Consolidating in #77333, which is fixed in 4.2.dev5.
