I am running heavy games like "Zombie Army 4: Dead War" and switching

Hi Mikhail,
thanks a lot for pointing this out.
Turned out that this is a known issue, but I've forgot to push the fix
to drm-misc-fixes and just queued it up for the next release.
Please re-test drm-misc-fixes and let's hope there is another -rc before
the final 5.12 kernel.
Thanks,
Christian.
