<a href="https://www.artstation.com/embed/3346607">https://www.artstation.com/embed/3346607</a> (source:
<a href="https://playrust.com/devblog-125/">https://playrust.com/devblog-125/</a>)
2. click the play button in the middle of the screen
3. GPU hangs before the object is displayed
Additional info:
- tested after a cold boot
- hang occurs every time (after a cold boot and after every GPU reset
due to a hang)
- /proc/sys/kernel/tainted = 0 (no non-GPL or out-of-tree modules were
loaded)
- also works under Firefox (both chromium and firefox have WebGL
acceleration enabled)
- the bug is also present on kernel 4.7.3 and mesa 12.0.2
- if intel_iommu is on, the PC may freeze completely
- DRI3 and SNA is enabled, but the hang also occurs under DRI2 / UXA
and the modesetting driver</pre>
