<pre>Hi,
(In reply to Hans de Goede from <a href="show_bug.cgi?id=90871#c34">comment #34</a>)
<span class="quote">> Ok' I've received this card now, and I can reproduce the problem. I'll

Ok, so as promised I've been investigating this one the last couple a days.
The fptest.c reproducer works to reproduce it, thanks.
At first I've tried different pitches / to swizzle / tile or not to tile on
various involved buffers on both the ddx and mesa side all to no good.
Today I had the bright idea (should have done that earlier) to run fptest
through apitrace and then glretrace, this resulted in the following messages:
27 @0 glXCreateWindow(dpy = 0x120b0f0, config = 0x125c9c0, win = 6291457, attri
27: warning: unsupported glXCreateWindow call
49: message: major api error 1: GL_INVALID_VALUE in glTexImage2D(invalid width
49 @0 glTexImage2D(target = GL_TEXTURE_2D, level = 0, internalformat = GL_RGBA,
49: warning: glGetError(glTexImage2D) = GL_INVALID_VALUE
88: message: major api error 1: GL_INVALID_VALUE in glTexImage2D(invalid width
88 @0 glTexImage2D(target = GL_TEXTURE_2D, level = 0, internalformat = GL_RGBA,
88: warning: glGetError(glTexImage2D) = GL_INVALID_VALUE
Rendered 2 frames in 0.0754768 secs, average of 26.4982 fps
The 27* messages are there when doing a glretrace on nv4x too, and the retrace
works fine on nv4x, so I believe that this warning can be ignored.
The problem is the next messages. It seems that something (not fptest directly)
is calling glTexImage2D with a npot width / height, where as nv3x is not npot
capable.
I'm a bit lost as to where this call is coming from, and as to whether or not
this is a fptest issue, or an issue with the code which is actually making the
glTexImage2D call. I'll ask Ben / Ilia for help.
Regards,
Hans</pre>
