I doubt any logging would help. Someone should try to reproduce this somehow using a version which is debuggable.
Then breaking in the debugger would reveal the problem and it would probably be an easy fix.
What are the settings of your rdp? Is it possible that the bit depth of the display is different? 16bits or lower? Can you build wxwidget sample and try the bitmap sample if it works correctly over rdp?
p.s. C::B is almost self contained. You need to build wxWidgets and C::B no other libraries.
And you must have zip in PATH.
