Description Michael Danilov 2018-10-19 15:51:34 UTC
When using 2D and 3D accelerated graphics I get corruption like missing/blinking characters in fonts, broken transparency and torn rectangles on screen, black with dark blue dots that sometimes move/blink, which sometimes also show up in textures.

Also I used to get GPU hangs (for 60 seconds, until the driver finds out and resets the chip) every half an hour or so of especially intensive use, such as switching workspaces a lot or running games/flightgear. But this seems to have resolved (though not completely, I have seen it hang like that again since, but it was only once) when I switched to modeset driver and drm-next-kmod.

Also I keep getting X11 crashes every 10 hours or so (of uptime -- of course the laptop gets suspended many times with X running), with the following backtrace:


I have reported these to FreeBSD, but there does not seem to be any activity at all:


Please help, I've been having these issues unresolved for so long now that I'm seriously considering buying a new computer and switching OS just to stop this.

My current setup:

FreeBSD 11.2-RELEASE-p2, generic kernel with drm-next-kmod-4.11.g20180822
xorg-server-1.18.4_9,1 using modeset driver

Lenovo B570e
Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz
