Hi,

Sorry for bothering again, but i still have this problem:

I have downloaded the latest cvs yesterday, but nothings happen.
I have tried out the -swaprgb option too, but i have the same problem. 

This is only happening at 16 bit, if i use 24 everything is fine.
I have an NVidia gForce 4, i use Fedora Core 2, i have tried out Xvesa,
Xfbdev too but the same result.

If You need more info please write me how can i get it and i will send
it to You.

Please help!
Thanks in Advance,
Julius
