Does:

xrandr -s 1360x864

work any better for you?  I find that I have to issue 2 commands since 
it "thinks" its already in the size I wish to choose, so I'd do:

xrandr -s 800x600
xrandr -s 1360x864

-s sets the screen size.  -fb sets the frame buffer size.  The frame 
buffer size needs to be large enough to hold the largest screen size, 
since a smaller screen size can be "scrolled" to view the entire frame 
buffer if necessary.  In Xorg.conf parlance, -fb is the "virtual screen 
size", and -s is the actual screen size.  When -s is smaller than -fb, 
the screen can be scrolled (via mouse movements) to view the entire 
frame buffer.

Of course, it resets everything from scratch.
