A quick update. I tested to see if kernel version affects this bug, and it appears not to. I booted up the previous installed kernel on my system (5.3.0-55) without the default options and got the exact same issue. Likewise, using the old kernel with nomodeset eliminates the corruption at the expense of hardware acceleration (inxi -G says my renderer is llvmpipe). As I didn't have this issue using that kernel on 19.10, I believe this points to something in the userspace that was updated when I went to 20.04.
