Recent Failure Reports:

Please describe your issue in as much detail as possible:

When navigating the steam link menus, after a short time the picture freezes. I can still hear the audio "blip blip blip" as the selected menu option changes, but the picture doesn't change. On the host PC, the steam app appears to be frozen - I have to "killall -KILL steam" to stop it.

My host PC is a dual boot Windows/Linux box. This problem only happens when running from Linux.

Logs:
steamlink_debug.txt
streaming_log.txt

Steps for reproducing this issue:

Start Steam client on Linux.
Connect using Steam Link.
On the Steam Link, navigate to installed games, move the cursor over various menu options until the video hangs.

Couple more data points:

I tried upgrading to Mesa 13.0.2. That didn't help, I still encounter this bug.

During this hang, steam is showing ~130% CPU use.

perf shows the top CPU users as:

After upgrading to Mesa 13.1.0-devel (git-3f5fba8) and kernel 4.9, I can no longer reproduce this problem.
