[pygame] Fullscreen perfomance problems

["John Eriksson" <john@xxxxxxxxxxxx>]

Hi,

I'm having huge perfomance problems when testing my game Slingshot in
fullscreen mode. There are no perfomance problems what so ever when playing
in windows mode.

I've tried both with and without hardware surface display. When trying to
convert the images there are a huge perfomance boost but then I loose the
alpha values.

I've also tried to use convert_alpha but without improvement.

The original images are PNG with alpha-channel.

Is there anything I can do or is it impossible to get alpha-blitting
perfomance in fullscreen mode.

Oh, yeah...I only have this problems on Windows XP. There are no problems on
Linux.

All ideas are welcome!

Best Regards
