Came across a strange bug on my i5/256 surface today. Booted up from cold and the screen was all washed out. All the colours were just really, properly washed out, not sure how to describe it. For the life of me couldn't figure out what was wrong. Went to change the brightness of the display (which was set to 75%) and just touching the slider (not increasing/decreasing the brightness) it just kind of all reset and the colours became more saturated at the same brightness level and is now displaying normally. Anyone else had this? First time it's happened to me.
