Inconsistent behavior / lockups under Mac OS X 10.5.4 #346

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Macbook Pro, OS X 10.5.4

What steps will reproduce the problem?
The first run of glcardtest.py after a system restart always works fine. Some 
number (0-15 or so) 
of runs later, it stops working. The pyglet window comes up, and I can verify 
that my main pyglet 
event loop is still running, but neither the cards nor the fps display appear. 
At this point I 
sometimes start seeing OS-level graphics glitches, or even complete system 
lockups. Sometimes 
I see the following in my console logger:

The image is larger than the maximum texture size.  pyglet doesn't currently 
check
for this before uploading images; apparently neither does your driver ;-)

You'll need to keep your images under 4096x4096, or under 2048x2048 for maximum
compatibility.

Thanks for checking into this.
I wondered if it might be due to the large size of the image. It seems strange 
that
this would cause the observed symptoms, however.

Is this limitation part of the OpenGL spec? Or is it dependent upon the GPU?

Item 21.130 at http://www.opengl.org/resources/faq/technical/texture.htm has 
some
interesting info.

Is the limitation only related to the number of pixels, (ie, is 8192x256 OK?) 
or does
each dimension really need to be 2048 or less?

Is 4 bytes per pixel (including alpha) pretty common? Does that mean that a 
2048x2048
texture consumes 16MB when uploaded to your GPU?
