Bug Description
a noticed graphics instability particularly with applications that have multi-range colorful graphics such as browsers and multimedia player. it has been the same experience for both Nvidia-driver-390, Nvidia-driver-340 and also nouveau-Xorg drivers. and the laptop even stucks at booting with Linux kernel 4.15.0-47-generic with no success to access tty1-6 terminal, as a result, I have to fall back to the previous kernel version to boot.

This sounds most likely related to temporal dithering (FRC) on the LCD screen.
Are you able to provide a video of the problem?
