Description Sylvain BERTRAND 2014-12-10 16:37:14 UTC
Up-to-date fedora rawhide, with up-to-date drm-next-3.19 linux kernel and mesa version 10.5.0 release 0.devel.3.29c7cf2.fc22 (bare openbox window manager).

While playing, small freezes happens while playing. Usually, it "blocks" for less that half a second, randomly. It's not really disrupting the gameplay as it's short enough, but it's quite ugly and surprising.

It seems, those mini freezes started to happen after the my last pull from drm-next-3.19 (see bug #86832)

Can you bisect?
Comment 5 Sylvain BERTRAND 2014-12-10 18:41:24 UTC
Ok, I dive in. The thing: for each kernel commit I should test I need to play hours to see if the mini freezes happen... this will probably take a while.

The only significant change in my dota2 configuration from the configuration, which seemed to work flawlessly, is that I play now in a 1920x1080 borderless window with openbox window manager, instead of 2560x1600 fullscreen with mutter window manager.

I'll try to locate a "good" commit from 26045b53c96f23b75a48544349c3d936e8402418

ok... I cannot reproduce the mini-freezes. They seems gone.
Driver would have been the wrong culprit.
