Description Vlad 2017-01-08 11:45:43 UTC 
Hello.

After updating to Fedora 25 applications that play videos started to hang periodically. Firefox, Chrome, Steam and mpv are affected when play video. Also I found that this can happen in 2d native games like Crimsonland. 3D games works just fine.
I can't find any logs related to this problem and the only manifestation of this is that the process goes into "futex_wait_queue_me" status and can only be killed.

One thing I noticed: starting mpv with --vo=x11 solves the problem. (default is --vo=opengl). It is 100% reproducible for me. 

I think the problem is driver related because I tried putting my ssd into another pc with Intel graphics and everything was working just fine.

More info in redhat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1401479

I don't know how to get more information but i'm willing to try if somebody suggests me.

My Hardware: 
AMD Phenom(tm) II X4 975 Processor
AMD Radeon 6850 GPU with r600g driver
