This is pretty likely to be a known problem with the resize support added in 
Xserver 1.8.2-1, see [1]

Unfortunately, due to a mistake on my part, there is no way to disable resize 
support in multiwindow mode in that version, so your options for a workaround 
are limited to:

a) Downgrade to the previous Xserver version
b) Use the test build provided by me in that thread
c) Avoid RDP sessions which change the colour depth of your display (e.g by 
setting your display to use 16-bit colour, assuming the RDP sessions choose 
16-bit for some reason)

If your problems persist with the that test build, I'd very much like to hear 
about it.
