gedit in openbox with 2.99.907 GM45 SNA

I am finding that GM45 SNA seems unusable with 2.99.907 - git bisect pointed to the bad commit as:
9289e2c56b7f0cc78c5123691ad96611f0e04bed is the first bad commit

    sna/gen4: Sacrifice performance to workaround render corruption

The problems are lines of text keep disappearing (and reappearing) in gedit, and the occasionally the screen becomes unresponsive for a short time and these messages appear in dmesg:

[ 1702.349954] [drm] stuck on render ring
[ 1702.349966] [drm] capturing error event; look for more information in /sys/class/drm/card0/error
