With the mouse scroll, it usually appears like the text is not moving (even though the point is actually moving). If I scroll with keyboard controls, the buffer partially redraws, usually in a ~32 character square with the point at the upper left. The screen will redraw correctly if (1) Emacs loses focus or (2) I recenter the buffer with C-l. This only happens when my third monitor is enabled, however. On my system, I have two monitors attached to the onboard Intel GPU, and one additional attached to an AMD GPU card. It makes no difference what monitor emacs is on, but enabling the monitor on the AMD GPU causes emacs to behave as described. Disabling the monitor (via xrandr) immediately fixes the problem. I do not observe this problem with any other software on my system, only emacs.
