[SOLVED] Video tearing after DPMS screen off (intel graphics)

I'm using the i915 driver and have TearFree turned on

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "sna"
   Option      "TearFree"    "true"
EndSection

It works great and I don't see any tearing, until DPMS kicks in and turns off the screen.

After the screen is turned back on, there is tearing.

I've looked into the xorg log and the system journal and couldn't find anything relevant.

Any help would be appreciated.

You're not the first one to notice this. Check bugs.freedesktop.org if there's a bug about it filed already. If not, someone should file it.

I have started using compton to prevent tearing instead of the i915 options for this very reason.

compton --backend glx --paint-on-overlay --vsync opengl-mswc

Thank you so much for that!
I was struggeling with tearing for so long. Tried everything. UXA/SNA Accelaration mode, tearing-off mode in d20-intel-conf - nothing worked.
compton finally did the job.
Add "-b" option for keeping it in the background.

Thank you!
