  It seems that whenever you take a screenshot within a 3d game, the blue

  Quake3, Quake2, and Kingpin and it happens on them all. I'm using a
  voodoo3 and Kain, who is helping Daryll Strauss, does not believe it's
  glide or the driver. Therefore, it would have to be mesa. Could someone
  experienced check this out? Thanks!
 
 How exactly are you taking the screenshot?
 Have you got a small demo program to reproduce the problem?
 


Related to the original message, I ended up sending a test
program to Daryll. I have not heard from him since, so 
I guess he is pretty busy with many issues...
(it was about two weeks ago)

my test prog did glReadPixels. When I tested it the
problem only appeared on my Voodoo2, not on Voodoo(1).

These both were with the win95 glide.

Also, intrestingly  the program first works ok, and starts failing
after a call to glutBitmapCharacter (glBitmap) is done.

Yep, I'm still here. I'm trying to work through a bunch of bugs and this
one is on the list.

So, that puts it directly in the Mesa driver bug category. It can't be a
Linux Glide bug, because you're not using Linux. :-)

Hmm. This sounds to me like a ARGB versus ABGR issue. I'll be taking a
look at it soon.
