--- Comment #8 from Zowie  ---
I suspect it's something different for Moyo Go Studio, but it could be. 24-bit
and 32-bit OpenGL bitmap rendering should already render pretty OK, so I
wouldn't expect the vertical lines for those. Nevertheless, I'll take a quick
look at it once I've got this fix merged.
