[Intel-gfx] drm/i915: Delay with fbc enabled

Fri Jun 24 01:23:08 UTC 2016

Hello,

since Kernel 4.6, the fbc is broken for me. Some specific X software
(e.g. wireshark-qt, sakura and sublime) display UI modifications, such
as keyboard input, with a delay up to ~1s.
Either downgrading to 4.5 or disabling fbc solve this problem.

This affects at least multiple Thinkpad and other users on Arch Linux:

I am no expert in this. So if I could provide anything more useful for
you, please let me know.
