RDP sessions often have a lower bit depth than the console (smaller color palette). Sounds like it could be a color-depth degradation failure. Can you make sure your RDP depth is as high as the regular display's?

RDP is very robust, and I have seen only a few apps that misbehave. If Tk is one of them, I'd like to check it out!

Assuming it's not the display bit depth, can you provide a hello world example that consistently does it? 

my $copilot = [ "Perl" ]
bless $copilot;
