Issue description

When I use the Godot Editor under a Wayland session on KDE Plasma, the editor freezes after I push the "Run the Project" or the "Remote Depuration" button. The game windows works fine, but the editor is completely frozen. It doesn't seem to produce a crash, and I can close it with the close button.

If I use the --display-driver x11 flag, the editor works fine and doesn't freeze. The same happens if I try it in a X11 session.

I've used WAYLAND_DEBUG=1 flag to make a log

wayland.log

Here's a sceen record of how it looks like:

Thanks for your report and thank you for the log! Thanks to it I was able to track the issue right away and I'm quite confident that the PR I'm going to make will fix the issue.

Unfortunately I don't have a setup with the latest kwin (shoot, I should really investigate on making a test rig or something), so you'll have to confirm whether the PR will work by testing it yourself for the time being, sorry.

All right, I made #94411. Please tell me if it fixes the problem :D

Closed this by accident, sorry!

Thank you!!!
I've just tried and it seems to be working fine now.
The editor doesn't freeze anymore when starting a scene.
