I set up my X to show about a quarter more width than physically visible on my screen. KDE/Kate dialogs like "open" or "save as" normally pop up with a width about max width minus a bit. On a X desktop like mine (1000 x 600 instead of physically 800 x 600) this results in the necessity to move my mouse left and right to see all parts of the dialog.

I think, it would be much better if KDE/Kate would take the physically max screen width as basis instead of the virtual max x size.
