I recently installed FreeDOS on a Ryzen system to get a parallel port device working. It boots fine but anything that uses graphics modes is flaky and will often hang the machine hard where Ctrl+Alt+Del doesn't work. SB16 compatibility is out of the question.
Curiously I got it into a weird mode where artifacts from a corrupted framebuffer in DOS were persistent on screen as a faint ghost image after booting into Linux even when cycling the power for a short duration. I have no idea how that could happen.

I have no idea how that could happen. This is most definitely a hardware issue with your display, not the frame buffer. What you describe would require alpha blending in software and couldn’t just “happen” with a linear array of corrupted bytes; it would require intentionality.
