Description

Before recent Xorg update I saw same errors only on heavy WebGL applications like games. Now it happens everytime.

It looks like: http://limbo.b1t.name/incoming/trash.png

Random errors in Xorg.0.log:

History

#1 Updated by arcade@b1t.name 8 months ago

Disabling KMS PageFlipping makes everything return to normal.

#2 Updated by zrj 8 months ago

Xorg and whole graphical stack so far still resides in DPorts/staged branch, DPorts/master is in a frozen state since Feb 6th.
If you run DragonFly-master it is likely caused by recent kernel changes.
On my R7 360 card I only see glitches in FF youtube window when overlays are present.
