Happens to me as well. Ubuntu 19.10 with a generic USB 3.0 Dock, and 2 HDMI monitors. Interestingly, the issue I have (among others) is that when I scroll down in a browser, for example, a 128x128 (or is it 64x64?) square of pixels around the cursor does not change from the original content pre-scroll. Moving the mouse enough resets this, after a second or two. This is super annoying when editing code, for example.
