primusrun or optirun bridge causes video artifacts when launching blender

[gavsiu]

Is anyone having these artifacts when launching apps with primus?

I've tried primusrun blender and optirun -b primus blender and they both causes these artifacts. Clicking the background and hovering over items "resets" this for each section.

Running optirun -b virtualgl blender has no issues. I haven't tried running any other app. I just wanted to see if CUDA rendering worked (which it does).
