Created attachment 1194725 [details] Xorg.0.log Description of problem: Some games that uses multicore rendering freezes few seconds after the game starts. First few second are playable. I don't have a huge selection of games, but from the ones I have The Beginners Guide and The Stanley Parable utilizing source engine both freezes with mat_queue_mode is set to -1 or 2. Q.U.B.E: Director's Cut that utilizes different engine also freezes on main menu after few seconds after menu appears. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-xorg-x11-drv-intel-2.99.917-18.20151109.fc24.x86_64 or newer How reproducible: Very well Steps to Reproduce: 1. Just start the game, freeze should happen in no more then 10 seconds in. Actual results: Game freeze Expected results: Game runs without freezes Additional info: With xorg-x11-drv-intel-2.99.917-16.20150729.fc24.x86_64 freezes does not happen.

Also, freezes does not happen Ubuntu 16.04.1.
The difference from Ubuntu is that Fedora enables DRI3 by default. I found out that following fixes freezes with recent xorg-x11-drv-intel. $ cat /etc/X11/xorg.conf.d/10-game_freeze_fix.conf Section "Device" Identifier "Intel_Graphics" Driver "intel" Option "DRI" "2" EndSection
If any developer needs a copy of The Stanley Parable or The Beginner's Guide to debug this issue, feel free to shoot me an email.
Two more Steam games that is having problems with DRI3 enabled: AdVenture Capitalist - In the lack of a term, screen is flashing with a random image constantly, game freezes eventually Viridi - Black screen for a split second, doesn't start
