I tried "Ubuntu on Wayland". Crash. Logged in. Screen loaded improperly and keyboard and mouse froze; handlers blocked and who knows what else. The screen didn't have the red artifact though; it had a cluster of diagonal black and white scan lines covering about the middle third of the screen, an incomplete population of the left hand tool bar icons I use and none of the desktop icons. The top tool bar seemed complete, but was non-functional.
Tried "Unity" while I was at it, and that was a complete flop post-log-in. Blank screen, except for an oversized audio slider icon at the top right and the cursor arrow, and the cursor was frozen; once again, no handlers.
