I am experiencing a regression in linux-image-generic-hwe-16.04 with
Intel HD Graphics 530 (Core i5-6600T), starting in 4.13.0-43
(considering only kernels which appear in my GRUB menu).
Some form of spatio-temporal dithering has been enabled. This is causing
a shimmering effect and visible dithering patterns (like woven textile)
which are noticeable on photographs and areas of similar colour. 1px
borders in the UI can appear to have a "marching ants" effect.
The effect is visible both under Xorg and in a virtual console
(Ctrl+Alt+F1), if the displayed colours are suitable to trigger it.
Booting 4.13.0-41 eliminates the temporal dithering.
This occurs on a (presumed) 6bpp laptop LCD panel, so dithering is
necessary, but in previous kernels only a form of spatial dithering is
applied, which is less visually obvious.
