Hey, did anybody try to have two transparent pngs displayed over each other? I tried to load the second over the first one, after bitblt ing the first to the screen, but it seems somehow the second one is not loaded perfectly it has noise in the background. I'm using it on linux with vesa. Can anybody help me? THX

The pngtest demo program does this, look at the source. But GRX doesn't handle alpha channel in contexts, so if you load a png file into a context and them biblt it to the screen, you lost the alpha channel.
