Is anyone else seeing artifacts when using X in base, with i915 Intel
graphics? [1][2][3]
I have 2 identical machines that experience this behavior, the artifacts
never stop appearing so X is fairly unusable. The artifacts are even worse with
fluxbox. I also see the following kernel errors often:
kern error:
[drm:(/usr/src/sys/external/bsd/drm2/dist/drm/i915/intel_sprite.c:132)intel_pipe_update_start]
*ERROR* Potential atomic update failure on pipe C: -35
kern error:
[drm:(/usr/src/sys/external/bsd/drm2/dist/drm/i915/intel_sprite.c:205)intel_pipe_update_end]
*ERROR* Atomic update failure on pipe C (start=13132 end=13133) time 5 us, min
1073, max 1079, scanline start 1076, end 1079
I’m was using a current build from April 27, I switched back to NetBSD 8 to
see if the issue is present there (as I’ve never used X on these machines
before.) The issue does not occur in NetBSD 8.
Thanks in advance,
Travis
