Hello, i need help. I fond now over 1 years the bug in team maui Go game, now i can play it, the problem was that the offBitmap is empty. in the BBmitmap the Color_Space B_RGBA32_BIG make the BBmitmap empty, when i edit to B_RGBA32 then goes it :-) So i look in /src/kits/interface/GraphicsDefs.cpp and found: const uint32 B_TRANSPARENT_MAGIC_RGBA32 = 0x00777477; const uint32 B_TRANSPARENT_MAGIC_RGBA32_BIG = 0x77747700; but i dont now what "0x77747700" do, it is wrong? I think it must set to "0x00777477" but this is the same a RGBA32. I hope anyone can help. -- Ralf Schülke aka Stargater
