Bug ID: 457141
Summary: Whenever Sceen Capturing FullScreen X11 Windows
Through Pipewire, video stream frozen once fully
focused on window
Product: kwin
Version: 5.25.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: hurricanepoo...@protonmail.com
Target Milestone: ---
SUMMARY
Whenever I select an X11 window to screen record on OBS, the recording freezes
as soon as the window becomes fullscreen. I was turned away from the
obs-studio's github and pipewire's github, and I'm now reporting it to the kwin
github, as both projects believe it's an issue concerning itself with kwin.
Let's say I'm playing minecraft, and the game is windowed. I can select the
window from the XDG desktop portal selector just fine, and in the recording, I
can see my game window and everything going on inside the game. However,
whenever the window I'm trying to record is fullscreen X11 window, it freezes
on the first frame of being full screen. Even if I select a windowed game, then
fullscreen the game, it freezes.
