Bug ID: 513538
Summary: kwin-wayland session is completely broken on RV380
while kwin-x11 works fine
Classification: Plasma
Product: kwin
Version First 6.3.6
Reported In:
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
I recently upgraded the debian installationon a National Instruments 8130 PXIe
embedded PC to the latest stable release and the default graphical session was
unusable.
STEPS TO REPRODUCE
1. Install KDE Plasma (here 6.3.6) on the National Instruments 8130 PXIe
embedded PC.
2. Use the kwin-wayland session which is selected by default.
3. After login, graphical session becomes unusable, windows do not draw
contents, Plasma desktop does not react to clicks, mouse pointer flickers.
4. Kill graphical session, change session type to kwin-x11.
5. After login, session works fine, Firefox and other applications are usable.
OBSERVED RESULT
After logging into a kwin-wayland session, the mouse cursor flickers and
sometimes draws a square with random content.
Windows restored from the last session are black or contain content previously
drawn in their place on the screen.
Closing windows is possible but takes tens of seconds.
Plasma desktop toolbar and widgets do not react to clicks, K menu does not
open.
Global shortcuts do not seem to work.
System log is continuosly filled with messages like:
kernel: [drm:radeon_crtc_page_flip_target [radeon]] *ERROR* failed to pin new
rbo buffer before flip
kernel: radeon 0000:01:00.0: 000000001d8f69be pin failed
EXPECTED RESULT
Desktop environment should work at least as well as in the X11-bases session
and not fill the system log with error messages.
