Bug ID: 516169
Summary: screen tearing freezes all chromium based browsers
Classification: Plasma
Product: kwin
Version First 6.6.0
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
screen tearing (kdisplay) freezes the image in chromium based browsers in
maximized (window) and full screen mode.
STEPS TO REPRODUCE
1. run chromium or derived (brave, chrome) in wayland (triggers with both video
hw decoding and without) with screen tearing ON.
2. open a youtube video and maximize
3. after a few seconds, the browser interface freezes completely until its
killed
OBSERVED RESULT
when the browser interface freezes (everything, video, UI, can't be moved), the
sound still continues and if you click on where the X is supposed to be you can
kill the browser.
EXPECTED RESULT
the browser should work just fine in maximized, fullscreen mode
