Bug ID: 99321 Summary: Videoplaying applications hangs on latest r600 Product: Mesa Version: 13.0 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: krnlbg@gmail.com QA Contact: dri-devel@lists.freedesktop.org

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.

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