--- Comment #13 from Gregor Münch <gr.muench@gmail.com> ---
Ive tested now some instructions enabled by Haswell according to:
https://gcc.gnu.org/onlinedocs/gcc-6.3.0/gcc/x86-Options.html#x86-Options
And found the culprit with:
-mbmi
Setting this and compiling mesa, corrupts Steam interface and also graphs
ingame enabled with Gallium_hud.
Since the instruction is also used on AMD since Piledriver, it would
interesting to see if those CPUs are effected as well.
