Hello, I am testing some OpenGL software that uses a DIB backed device context followed by a BitBlt operation to draw graphics on to an on-screen canvas. Unfortunately this does not seem to work. I have tried to patch the latest wine with DIB engine patches (bug 421), but, was unable to get it working still. My question(s) are: 1) Is this a known issue? 2) Is it in the scope of the DIB engine to fix this? and this is slightly OT, but 3) Are there any alternatives for drawing OpenGL in to a invisible buffer in a cross-platform transparent way? I found the some simple example code here, that is quite small and able to replicate the problem: http://stackoverflow.com/questions/4052940/win32-how-to-make-an-opengl-rendering-context-with-transparent-background I would really appreciate any input as I am a bit stuck at the moment. -ravi -- C-x C-s, C-x C-c
