Description Donny Viszneki 2009-01-03 12:09:40 UTC 
Standard RGB/BGR switch problem. I stepped through the video initialization process on my system and noticed that if I ask for 24-bit color with SDL -- or if SDL decides for 24-bit color when I pass zero for the bpp argument of SDL_SetVideoMode() -- then red and blue color components get swapped. If I pass 32 as the bpp argument, all is well. I will attach a source code to demonstrate the issue.

I tried attaching a file, but Bugzilla gave me this message:

undef error - Undefined subroutine Fh::slice at data/template/template/en/default/global/hidden-fields.html.tmpl line 58

You can find the file test-color.c as an attachment here:

I think I fixed this in the latest snapshot.  Can you take a look?
