Title:
Severe graphics regression with mainline kernel v4.7.5 on Broadwell
5500U
Status in linux package in Ubuntu:
Incomplete
Bug description:
I would like to report a severe graphics regression, involving
frequent rainbow-glitching and flickering on a x64 computer with Intel
Broadwell 5500U processor w/ integrated graphics. This issue was not
present on kernel v4.7.4, which I will continue to use. Due to
unfortunate issues with Broadwell integrated graphics support,
virtually every kernel build in the 4.8 release chain as well as the
newest v4.7.5 kernel have this issue. Dramatic multicolored patches
and glitched areas appear frequently when using my computer with these
kernels installed. The behavior is very similar to that of the
Broadwell graphics issues present in kernel version 4.6.x. Please fix
this issue, I don't understand why NEWER kernels are actually causing
significant graphical problems with older hardware.
