Hi,
First I am using clutter 0.8.4 on win32 with an RADEON 9800 PRO.
I join to this mail a very basic sample (50 code lines) that compare :
- cogl_texture_new_from_foreign and CGL_TEXTURE_RECTANGLE_ARB
with
- cogl_texture_new_from_foreign and CGL_TEXTURE_2D
This is the output debug I get with CLUTTER_DEBUG=all:
As you see "cogl_texture_new_from_foreign" fails if I am using
CGL_TEXTURE_RECTANGLE_ARB.
Moreover I get same result on Ubuntu 9.04.

clutter version: 0.8.4
has texture rectangle ? 1
valid cogl handle for CGL_TEXTURE_RECTANGLE_ARB ? 0
valid cogl handle for GL_TEXTURE_2D ? 1
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Could you explain why cogl handle is invalid when using
CGL_TEXTURE_RECTANGLE_ARB ? Can someone test it on clutte 0.9.2 ?
(I looked at the clutter code but it was not 0.8.4, it was 0.9.2. I could
not figure out where clutter return COGL_INVALID_HANDLE in the
"cogl_texture_new_from_foreign" implementation.
I mean there is a lot of checks, I have checked too by myself, and every
thing seems to be just fine)
Sincerely
Julien
