<pre>There were improvements pushed in kernel, xf86-video-intel and Mesa that will
benefit to your system, so please re-test with latest kernel, xf86-video-intel
(in case you use SNA) & Mesa to see if this issue is still occurring.
Mark as REOPENED if you can reproduce (please capture and upload an apitrace
(<a href="https://github.com/apitrace/apitrace">https://github.com/apitrace/apitrace</a>) so that we can easily reproduce as
well.) and RESOLVED/* if you cannot reproduce.
In both case, please confirm your environment (see below)
* Details:
- Kernel: 4.8.13-1-ARCH
- Platform: Skylake (PCI ID: 0x1916, PCI Revision: 0x07, PCI Subsystem:
17aa:504a)
- Mesa: [Please confirm your version]
- xf86-video-intel: [Please confirm your version]
