--- Comment #2 from M <manuel.snudl.zeid...@gmail.com> --- Yes, unfortunately it still is (git f3858d1), with optirun as well as primusrun. The flickers only become apparent once a document is opened or created, and only when there is any movement on screen. No issues with 4.1.8. Another way of avoiding it is starting an X session on the Nvidia GPU directly. In the terminal I see these lines repeated only with primusrun or optirun: qt.glx: qglx_findConfig: Failed to finding matching FBConfig (8 8 8 8) qt.glx: qglx_findConfig: Failed to finding matching FBConfig (1 8 8 8) qt.glx: qglx_findConfig: Failed to finding matching FBConfig (1 1 8 8) qt.glx: qglx_findConfig: Failed to finding matching FBConfig (1 1 1 8) -- You are receiving this mail because: You are watching all bug changes.
