Bug ID: 493157
Summary: Screen stuck flipping between frames
Classification: Plasma
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: jhanm...@ca.rr.com
Target Milestone: ---
SUMMARY
Screen appears to be stuck while system continues to operate in the background.
Since screen drawing is dead/locked continued operation of the applications is
not visible. I can switch to other system consoles (text consoles) using
Ctrl-Alt-F3-Fx and they are still functional. I can kill the Plasma session by
finding the started session and killing it. That immediately drops me back to
the SDDM login screen. I can login to another sessions it it will work for a
while until the problem recurs. This only happens with Wayland. X11 sessions
appear to work without ever locking up.
Applications running when the screen freeze occurs run normally to completion
if I wait for them. I simply can't see what is going on.
I thought this might be due to the new triple buffering feature so I tried
disabling that via putting KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1 in
/etc/environment. That appeared to have no effect on the problem.
TTF is somewhat random. I can sometimes operate for hours while other times it
occurs within minutes. I've waited for the system to recover but after several
minutes it remains in the same non-function state.
No messages appear in the systemctl journal or the dmesg log when the failure
occurs.
No triggering cause seems apparent. My actitivites when the screen freeze
occurs is random.
OBSERVED RESULT
Screen freezes. Sometimes it appears to flip between two (or perhaps a few
more) frames rather than being just frozen on a single frame.
EXPECTED RESULT
