Could be the case. Bug is hard to reproduce because it happens only in games
and at random intervals. And you can't idle it. Sadly I don't have much time
for gaming now. I'll try it one more time, more thoroughly.
One question though, if I'm 100% positive that v3.16 is good, should I skip
bisects (mark them as good) if they end up as 3.16.0+ image after bisect ?
Thus testing only v3.17 bisects.
Because out of 7 steps 3 were from 3.17, it can save a lot of time if I could
skip 3.16 bisects.
