In order to show the artifacts you should rotate the point of view or zoom the objects several times. This bug may be related to bug nr 108282. Hi. Thank you for report. I reproduced issue with graphic glitches, going to bisect it. Issue can be reproduced only after applying fixes from https://bugs.freedesktop.org/show_bug.cgi?id=108282 Unfortunately, the reason of that issue is the same commit as for https://bugs.freedesktop.org/show_bug.cgi?id=108282: commit a363bb2cd0e2a141f2c60be005009703bffcbe4e Author: Kenneth Graunke <kenneth@whitecape.org> Date: Tue Apr 10 01:18:25 2018 -0700 i965: Allocate VMA in userspace for full-PPGTT systems.
