SuperTuxKart in 18.04 : flickering shadows with intel i915

Coming from Graphics flickering issue 19.04

Adding a file
/etc/X11/xorg.conf.d/20-intel-graphics.conf
containing

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

seems to fix my flickering issue sor far… time will tell.


and no, not fixed…
It seemed to have an effect on flickering ( maybe less frequent, maybe less flashy ) but still there.
