Bug ID: 494108
Summary: System stuttering, freezing: kwin_wayland[1897]:
kwin_scene_opengl: Invalid framebuffer status
Classification: Plasma
Product: kwin
Version: 6.1.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---

journald log
SUMMARY
Sometimes (trigger unknown) a kwin_wayland bug appears, causing every graphical
action to stutter heavily, basically as if FPS on visual effects was one frame
per few seconds. In between, the system is frozen. This makes the system
unusable (can't use mouse, pad, or basically any visual trigger). Even using
keys, the effect shows with strong delay.
STEPS TO REPRODUCE
1. Upgrade from Plasma 6.1.4-1 -> 6.1.5-1
2. Trigger unknown, but usually happens when watching YT videos, but
occasionally.
3.
OBSERVED RESULT
The system becomes unresponsive, almost impossible to control visually with
mouse, pad or keys, because every visual effect shows after few seconds, while
in between everything is frozen. There is no increased CPU or memory usage.
Journald shows infinite error lines:
kwin_wayland[1897]: kwin_scene_opengl: Invalid framebuffer status:
"GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"
EXPECTED RESULT
No kwin_scene_opengl: Invalid framebuffer status bug, system works normally,
fluently as usual.

ADDITIONAL INFORMATION
I noticed, that the log lines have wrong time, an hour behind of what my time
is set. So instead 14:46, journald shows 13:46. I'm not sure if that have
something to do with the bug, but it's worth mentioning.
Most of the time the system works fine, but since this happens irregularly
after Plasma update, I can't live with. After some time, I will have to restore
the system from backup, so the bug is really severe. I'm trying to wait a bit,
because maybe some additional info is needed, but this is a showstopper.
