Public bug reported:
Hi,
for few weeks now, I've noticed a big change in graphic performance
while playing famous SuperTuxKart on ubuntu bionic :
shadows are flickering, all over the screen, it's a big pain for eyes (
and wonder what would happen for epileptic people ).
My computer is :
Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz with 16Go ram and Haswell integrated
graphics.

IMPORTANT NOTE #2 :
I have also tried newer version of mesa through padoka's ppa (
https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa?field.series_filter=bionic
) on 18.04 but it did not change anything.
