Bug ID: 467959
Summary: kwin_wayland crashes when screen recording with OBS
29.1 beta
Classification: Plasma
Product: kwin
Version: 5.27.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Testing OBS 29.1 Wayland via flatpak there capture errors like flickering,
jumping images, blackscreens. Investigating further it developed into a
reproducible kwin_wayland crash.
STEPS TO REPRODUCE
1. Install flatpak
2. Add flatpak beta: "flatpak remote-add --if-not-exists flathub
https://flathub.org/repo/flathub.flatpakrepo";
3. Install obs-studio beta: "flatpak install com.obsproject.Studio"
4. Start capturing video with "Screen Capture (PipeWire)" or "Window Capture
(PipeWire)"
OBSERVED RESULT
Capturing video results is distorted, esp. if the mouse pointer is moved above
the OBS capture preview or the captured window (screen). A informal chat over
at the OBS discord was hinting to a potential plasma upstream issue.
Testing on a different machine and distro confirms and also leads to
reproducible kwin_wayland crashes.
Video example for both in attachment.
EXPECTED RESULT
Capturing video without flicker, blackscreen or crashes (as in OBS 29.0.2 and
prior).
SOFTWARE/OS VERSIONS
Included in file attachment.
