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

Thomas,

Yes, it is similar in that it is likely that some surface is being lost 
and we are not restoring it.  There were several places in the code 
where I made a decision not to look for lost surfaces because it did not 
seem that we could ever lose a surface at those points.  However, I 
think that in this case we might actually be losing the offscreen 
surface, as opposed to the usually lost primary surface, and there is no 
code in place to look for or restore a lost offscreen surface.  It 
wouldn't be hard to add such code for the DirectDraw engines.  Of 
course, we have to identify the problem first.
