[Plib-users] works with Mesa 3.3?

[Steve W. <st...@sh...>]

Has anyone tried using plib 1.2 with the 3Dfx Mesa 3.2.1 or 3.3?  First I tried 3.3, 
which seemed to have some problems of its own (like #including glext.h, and not 
copying it when you do a make install), as well as causing pui to really screw up 
when using glide on my Voodoo2.

I switched to 3.2.1 (which had no internal problems that I could see), and it has the 
same problem:  the top of the screen is either severely distorted or blank, both in 
windowed and fullscreen modes.  Software mode (MESA_GLX_FX=d) works fine.  
The problem occurs in both tux:aqfh and tuxkart, so it's not my code.  :)

I haven't tested other OpenGL apps yet (I should), but is this more likely to be a 
Mesa or plib problem?  Did something get fixed in Mesa that plib was "working 
around," or did something in Mesa break (which seems less likely, since they put 
some 3Dfx specific fixes in this one)?

Not yet.

Hmmm - not good - but then 3.3 is experimental/unstable.

Can you either describe this more carefully (What *exactly* do you mean by "severely
distorted"? Does it flick back and forth between 'distorted' and 'blank' in a single
run - even if the eyepoint is stationary?  When it's "blank" - is it black or some
other colour?) - or better still, post a screenshot to a web site somewhere (or if
you must, email to me *privately* - not to the list).  I'm particularly interested
in seeing the "distorted" case - that'll tell me much more than the "blank" case.

PLIB doesn't do anything special at the top of the screen - it doesn't even know
when it's drawing at the top of the screen.  I havn't seen this problem on any other OpenGL
implementations - so it's pretty certain to be a Mesa problem - but I *really*
need either a very careful description or a screen dump.

Also, it's working in software mode - and since what Mesa does internally in
software and hardware modes is drastically different - but PLIB does the exact
same thing in both cases - we have to expect Mesa to be at fault.

Nope - nothing that I'm aware of.

Let's see the screen dump before passing a final opinion...but I'm betting
on Mesa.

This is definitely a Mesa problem, other, non-plib apps have the same problem -- 
approximately the top inch of the screen is black when in 3Dfx mode on my 
Voodoo 2.  I guess the new Mesa fixes were tested on Voodoo 3, Banshee, or 
Voodoo 5.  :(   I guess I will stick to Mesa 3.2 until the next release comes out.

Have you posted this to the Mesa list?

It's very important that they get this kind of feedback.

Nope... not on that list.  Last I looked, it was too high traffic for my interest level.

Either that or use the bug-tracking tool at
http://sourceforge.net/project/?group_id=3
Look at the sample bug report first.
AFAIK, if you report a Mesa-bug and it is closed, you will
automatically get an E-mail.
(BTW, does anyone know how to close bugs in the Sourceforge bug
tracker?).

Bye bye,
