[Chromium-users] GL_MAX_TEXTURE_SIZE returning 0

[Vincent V. <viv...@ir...>]

Dear all,

A collegue is trying to run an OpenSceneGraph application through Chromium.
However, any application with a textured scene segfaults.

After some investigations, I found that OSG relies on GL_MAX_TEXTURE_SIZE
to resize a TEXTURE_2D to the nearest power of 2.
Under a Chromium cave configuration, GL_MAX_TEXTURE_SIZE returns 0,
therefore OSG tries to allocate a texture of (0,0) size which causes the 
segfault.

Could anyone confirm that bug ?

Regards,

Vincent

The piece of code to insert within osgviewer render loop :

GLint   _maxTextureSize;
glGetIntegerv(GL_MAX_TEXTURE_SIZE,&_maxTextureSize);
printf("GL_MAX_TEXTURE_SIZE : %d\n",_maxTextureSize);


My configuration :

3 linux PC under Fedora 5
GPUs : ATI Radeon X800 GTO  with fglrx drivers / the situation is similar with NVIDIA GPUs. 

OSG version : 1.2
Chromium version : 1.9.
