--- Comment #2 from Eero Tamminen <eero.t.tamminen at intel.com> ---
In last nightly [1] things got worse:
* Unigine (onscreen) Heaven & Valley demos now run mostly with minimum GPU
frequency too
  - I think that as result the CPU side is also run slower as demo startup and
scene changes take longer, but it's hard to say which one is cause and which an
effect
* There are now GPU hangs (in 2 different test-cases)

Last nightly was run with modesetting driver instead of Intel DDX, but I don't
think that's related as there's no similar Unigine demo issue in Mesa testing.


[1] I.e. from changes between:
