The apitrace file that can reproduce the flicker
Opening some website in chrome/chromium can cause screen flicker on my kaby
lake laptop. The screen will flash violently and display some garbled content
on a black background. It's gone as soon as I close the offending tab with
keyboard shortcut.
I tried to make screenshot during the flicker, the screenshot image looks all
right, so that might be a display issue rather than rendering one. I captured
the rendering commands using apitrace, and found replaying the trace will also
cause the flicker. The trace is also attached here. I don't think I have found
anything helpful in kernel or xorg logs. This occurs with both xf86-video-intel
and modesetting driver in xorg.

Machine: Acer Aspire VX5-591G-72LY
