Options window scaling masks options

When I use the options window some of the options at the bottom of the window are cut off. By changing the scaling number the window size changes in an irregular fashion hiding or revealing extra options. all the options appear (not cut off at the bottom) as the scaling increases past 110%. Is this a bug or my settings?
