Bug Description

Provided you have an output called LVDS1 that is capable to show 1024x768 resolution, after running
xrandr --fb 1154x864 --output LVDS1 --scale-from 1154x864 --mode 1024x768
try to move mouse pointer to the right-bottom edge of the output. It should move there, but it does not.

I want to use the scaling to output to 16:9 TV in right aspect ratio:
xrandr --fb 1024x576 --output LVDS1 --off --output TV1 --scale-from 1024x576 --set mode PAL --mode 800x600
However, if I run
xrandr --fb 1024x576 --output LVDS1 --mode 1024x768 --output TV1 --scale-from 1024x576 --set mode PAL --mode 800x600
mouse pointer can be moved to the bottom-right corner of the TV1 output (minus possible marginals).
