--- Comment #8 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Do you by "transient" mean that leakage has some trigger condition when it
starts, and that it doesn't happen before that?
I don't think there's been any change in how things are tested, and performance
numbers both in our own testing and at QA have been for few days about [1] at
same level as before.
[1] This test has very large variance like other CPU / scheduling depend tests,
and can be affected by "unrelated" changes elsewhere than in 3D code, so it's
hard to say whether it's exactly at former level.
