Impact: when cirtain resolutions are selected the screen is staggered in a diagonal fashion

===
Binary package hint: xorg
Step to reproduce:
Go in monitor
change the resolution for 1600x900 to 1360x768 and apply change
Expected result:
resolution change and display is usable

the pointer wraps from right to the left

Can you reproduce this issue when booted to Classic Desktop (no effects)?
Try using the xrandr command line tool to change resolutions and see if the bug reproduces with that too.
E.g.
xrandr --output LVDS1 --mode 1360x768
