Just had a monitor fail in the most bizarre way posible. I got some weird screen flicker/tearing. I assumed that it was my video card doing someting wonky, especially since it would happen sporadically when playing Minetest, and would often persist for a while after. A reboot cleared it the first time it happened.

This time it was really bad though. The weird thing is that when I disconnected the HDMI cable, the distortion persisted on the OSD. Also, there was still very distinct remnant of the image that had been on the screen. It wasn't your typical burn-in, as it wasn't static. It was just... weird.
