Bug ID: 514179
Summary: Window flickering in OBS recordings
Classification: Plasma
Product: kwin
Version First 6.5.4
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: screencasting
Assignee: [email protected]

Target Milestone: ---
SUMMARY
Windows (most notably Steam) visibly flicker during full-screen OBS display
capture on Wayland. The flickering does not occur when using a rectangular
region capture that covers the entire screen.
STEPS TO REPRODUCE
1. Log into a Wayland session in KDE Plasma
2. Open OBS Studio and add a Display Capture source
3. Select an entire monitor/output
4. Start recording
5. Observe visible window flickering in the OBS preview that also persists in
the final recording
6. Open the Display Capture properties and configure it to use a rectangular
region covering the entire screen instead of a specific output
7. Start recording again
8. Flickering does not occur
OBSERVED RESULT
Visible window flickering occurs when recording a specific display output.
EXPECTED RESULT
Recording a specific display output should not cause window flickering and
should behave identically to region capture covering the same area.
