Hi, I've experienced a few graphics issues recently, and I tend to believe that it has happened since 4.4-rc. Namely, after some long time usage on my HSW laptop (two or three days), the mouse cursor vanished suddenly. It kept pointing but just became invisible. Also, after some S3 cycles, some glyphs on a console or on Firefox became invisible, too. The windows and graphics were shown well, and X core fonts were still shown properly, too. Switching to VT1 and back didn't change the situation. There were no obvious errors or GPU hang in both kernel and X logs when these happened. Also, the issue was gone once when I restarted X even without reboot. (But then it seems re-triggering the bug more shortly.) I've had this a few times and never had this before 4.4-rc1. It's intermittent and very hard to reproduce. Possibly triggered by a high memory usage or such. Also today I experienced a similar mouse pointer vanish on an IVY desktop. Though, I cannot judge whether this is the same cause. Since I'm using openSUSE Tumbleweed that is a rolling release, I can't blame only kernel. But, my gut feeling tells it's probably a kernel regression, something like a cache issue. Alas, it's impossible to bisect due to the difficulty of bug reproduction. Can anyone give some hint for debugging once when this problem happens again? thanks, Takashi _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
