Flickering while playing videos on Chrome
I have 2 laptops from ASUS (X542UQ KabyLake + NVIDIA 940MX and X507MA
GemniLake) which will have the flickering problem while playing videos in
https://yandex.ru/video/search?text=%D1%84%D0%B8%D0%BB%D1%8C%D0%BC%D1%8B%20%D0%BF%D1%80%D0%BE%20%D0%BA%D0%BE%D1%81%D0%BC%D0%BE%D1%81&path=main&reqid=1513175428905465-1641906819282495832002859-man1-4483-V.
Please reference the attached file that I've recorded. It keeps showing the
while macroblock and the interesting thing is it won't happen while I play the
same video clips on youtube. And it won't be a problem playing with Firefox.
But why I'm so sure that it's about i915 driver is due to everything good after
I disable i915 while booting. It's good after I switch to NVIDIA drm on X542UQ
and disable i915 on X507MA.
I also tried the kernel 4.13+ and 4.15+ but nothing changed. Then tried to
build my own kernel from the current head of drm-intel-next-queued branch on
git://anongit.freedesktop.org/drm-intel, the problem still remains. And maybe
one thing worth mention even I don't know it causes confusion or does help.
When I compiled the kernel with CONFIG_DRM_I915_ALPHA_SUPPORT=y, things would
get worse. The white macroblock shows more frequently.
Any suggestions?
