Bug report: Using Cygwin-Xfree through Remote Desktop Sharing (RDP)

[Harold L Hunt II]

Jean-Claude,

Repeat the entire scenario you described, but start XWin with the 
``-engine 1'' parameter, e.g.
XWin -engine 1

The default graphics engine on Windows 2000/XP will be DirectDraw 4.0; 
DirectDraw will probably have a problem with RDP --- I am surprised that 
it works at all.  The ``-engine 1'' parameter will tell XWin to use GDI 
DIBs (Device Independent Bitamps) and regular GDI BLTs (Bit-Block 
Transfers) as the graphics engine; GDI will be less prone to having a 
problem with RDP.

If RDP works with the GDI engine then I know exactly what to fix; if 
not, I will have to pump you for some more information.
