Currently, I use intel_drv with SNA. I have compositing enabled (opengl

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
