Bug ID: 361763
Summary: plasmashells always locks up with modesetting driver
Product: plasmashell
Version: 5.6.1
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: jirisl...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Currently, I use intel_drv with SNA. I have compositing enabled (opengl 3.1).
When I switch to modesetting_drv, plasmashell "locks up" few seconds after
start. The trigger is perhaps hovering over icons in the tray.
The lockup is that X spins with drm_ioctl_wait_vblank and other ioctls on one
CPU 100%. When I do:
killall plasmashell ; plasmashell
X stops spinning until I hover over the icons again.
So plasmashell has some problem with rendering, I suppose. I tried both OpenGL
and XRender compositing. Note that this also happens without compositing
enabled at all.
Reproducible: Always
