Hi,
> Have there been any changes to OpenGL libraries in 32-bit cygwin in the last six months?
i also have another OpenGL app crashing.
glxinfo reports wrong Video memory size.
glxgears raises SIGSEGV under swrast_dri.so.
i could not reach exact crash point, b/c dri-drivers looks having no
debuginfo package ATM.
maybe, mesa (or something for GLX) is simply broken?
Peace,
