[ 2009.308943] [drm] GPU HANG: ecode -1:0x00000000, reason: Kicking stuck semaphore on render ring, action: continue

[ 2009.308959] [drm] GPU crash dump saved to /sys/class/drm/card0/error
Identifier "Intel Graphics"
Option "AccelMethod" "sna"
Option "TearFree" "true"
The problem occur very often, the screen flashing and I have to change the position of the object to refresh it and to stabilize a view, sometimes the screen freeze and then only hard restart helps (console not answer).
Now screen with option TearFree is more stable but this not fix the problem, with TearFree the problem does not occur all the time.
In attachments You can fins a error dump generated by Xorg I hope this will helps.
Also I changed the acceleration to uxa, but this nothing change for this problem.
