Current Behavior

Whenever I use monitor setup with screen orientation other than 'normal' (e.g. rotated right), the background image is rendered with a wrong width

Expected Behavior

the bg image rendering counts the screen orientation in and e.g. in setup with screen rotated 90 degrees, it works with screen resolution's height instead of width

Reproduction Instructions

just use some screen manager (i use arandr) to rotate your screen 90 degrees.
Reproducible on single monitor setup as well
