Trying to upgrade to a more updated Mesa version from the Mesa 18.0.5 shipped
with Ubuntu 18.04.1 as suggested by SCS Software Customer Support to resolve
framerate issue on Euro Truck Simulator 2 happened after the 1.33 update of the
game (that haven't resolved), I experience graphical glitch of missing texture
that appear randomly as popup on every game, not only on ETS2.

I have tried all the PPAs quoted on the summary, but only the 18.0.5 doesn't
have this issue.

I will attach a video recording the issue for better comprehension of the bug
playing two games to show is not limited to only one game
