What you are seeing is probably the most literal demonstration of bit
rot I can imagine. It sounds like the effect one gets from turning off
the drive to the LCD panel, but leaving the back-light on. It's very
odd looking.

Most likely something in XFree86 is telling the video card to do
something it does not like and, rather than drive the screen with
potentially damaging signals, it just turns off.

When you went from 4.8 to 5, did you hange versions of XFree86? Is the
XF86Config file changed? Sounds like something must have changed in
the XFree86 stuff that really upset the graphics system to the point it
simply turned off.
