On my m3-6Y30 skylake HD Graphics 515 (rev 07), it causes visual artifacts that look like bunch of one pixel high horizontal streaks, seen most often in firefox while scrolling or in menu controls. Reverting this patch on top of current mainline fixes the problem. _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
