I did some binary-search like investigation.
The issue starts with 0611 build. every build before 0611 is fine.
Quote:mesa: update to mesa-19.1.0
The bump to mesa-19.1.0 is possible, but #0611 also bumps to kernel 5.1.9 in which the Gemini Lake framebuffer compression is disabled, which may be a more likely cause for this issue - the framebuffer compression causes graphical corruption of the top part of the display. Are you disabling/enabling or otherwise modifying the framebuffer compression behaviour on your hardware via the kernel command line (the option is [inline]i915.enable_fbc[inline])? If so, remove any framebuffer kernel command line options and see if that helps - the default should now be fine (ie. disabled).
