I just built Cygwin/XFree86 with RENDER, LAYER, and RANDR disabled. I can log on to KDE 3.0 running on a remote machine with the Windows display set to 32 bits per pixel and all the KDE icons display correctly. It looks like Waldo was right-on about the alpha channel problems.
I was intially trying to disable just RENDER, but then something it layer failed to build when I disabled RENDER, so I had to disable LAYER and RANDR as well. Now we just need to find out if RENDER is having a problem with our visuals and/or pixmap formats or whether Qt or KDE has some problem that causes alpha channel rendering with our visuals and/or pixmap formats to not work. I'll try to build Cygwin/XFree86 with RENDER but without LAYER and RANDR to see if that still fixes the problem. Harold
