SUMMARY

Changing window state (maximized <-> fullscreen <-> non-maximized): OBS Studio window recording freezes.

I am not sure if this a an actual KWin, Plasmashell or rather an OBS Studio, Pipewire or portal issue. Sorry in advance if I filed it against the wrong product. :)

TEPS TO REPRODUCE
1. Open OBS Studio 29.02 Wayland
2. Add a window to your sources, e.g. Firefox or Dolphin
3. Change the window state: Maximize it, make it fullscreen or drag it so that it becomes a non-maximized window

OBSERVED RESULT
OBS Studio's preview (recording) of the window becomes frozen.

When this happens journalctl logs
