I have this problem, but I've also seen the UI freezing or locking up
(most of the time) when you minimize applications. If you press Alt +
Ctrl + Del and get the shutdown diag, it goes back to normal.
I wonder if it's part of the same bug or a different one?

I have tried the solution from comment #6 and it works. It would be
helpful to understand why this works. Digging through the comments it
looks like mesa uses not the GPU acceleration when the variable is not
set. This looks like a design error in mesa. Maybe mesa developers
should be asked about
@manny that is a different bug.

I was able to confirm the lockups happening also on an AMD/ATI laptop.
However, I get much more lockups on the Intel.
So anyone else experienced this or reported it? Else I'll go my way and
report this soon.
