Created attachment 81723 [details] Photo showing the issue I'm using live xorg with Radeon HD5450. I have two monitors connected and I wanted to set up the second monitor right of the first one with some invisible space added (to avoid window shadows leaking to the second screen). I've noticed that with some --pos values (especially odd ones), a line of cruft is drawn on the left hand side of the screen. I've attached a photo showing that line. For example, I see a similar line when using: $ xrandr --output VGA-0 --pos 1350x0 (with the other screen running at 1280x1024) However, the exact shape and colors of the line differ with every xrandr call. I suspect it has something with modulo 8, maybe memory clearing issue or something like that.
