After building from your snapshot I have not been able to reproduce this
specific problem. I tested with and without the -resize option (I
believe I read in the archives that -resize was unintentionally always
in effect in the version with the bug).
I haven't had a chance to try the new 1.9 build yet.
I did encounter a strange crash the first time I ran the snapshot build.
I was already running an Xming server, and the Cygwin server started
without any issue but crashed as soon as I started a client. The
backtrace made little sense to me -- it contained only two frames, the
top being the GetDC API, and below that an unknown frame. Perhaps any
unknown frame can give incorrect results below it, and obscure the true
call stack? Unfortunately even the source of the unknown frame was
missing (if I recall correctly), so there was no easy way to determine
what additional debug information might be needed.
Is it possible that the Windows Xorg port (which I take it is the basis
for both Xming and Cygwin/X) does not support or properly handle running
multiple instances concurrently?
Whatever the case, the immediate problem does seem to have been
resolved. Thank you!
