Description Thomas McGuire 2004-11-02 15:55:48 UTC 
Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:                Linux

The title says it all: If the resolution is lowered, for example from 1024X768 to 800X600, the right and lower desktop border no longer work.

I guess this is because kwin still checks if the mouse reaches the 1024th pixel, despite only 800 pixels being available.
