I am facing the same issue with Intel HD Graphics 520 [Skylake GT2]. On switching to Ubuntu Wayland, the artifacts are gone.

These artifacts go away when I enable Option AccelMethod "uxa" but persist if the default, "sna" or the other modes are used "none", "off", "blt". These pixels appear throughout the experience of using Ubuntu and generate in sporadic places. The font also looks completely broken. I've never had this issue before with the Intel drivers. I have Skylake HD 530.
