[Mesa-dev] nv3x xfce4 compositing issue, making good progress, need help / input

[Hans de Goede]

Hi,

I've been working on trying to fix this one:

https://bugs.freedesktop.org/show_bug.cgi?id=90871

And today I've more or less root caused this, it seems
that some code is making glTexImage2D calls with npot
width / height, which fails on nv3x (where as it works
on nv4x).

The bug has a simple reproducer attached, but that is
not directly calling glTexImage2D, so it seems that
the npot values are coming from some helper library
used (glXBindTexImageEXT  ?).

2 questions:

1) Does anyone know / suspect where the glTexImage2D call
is originating from (see the test-program attachment
in bugzilla.

2) Is this a bug in glXBindTexImageEXT (assuming that is
the culprit), or should the test program take into account
that the card does not support npot when calling this ?

Thanks & Regards

Hans
