I have an OpenGL (Mesa) application that works fine except when I attempt to render
the same texture objects in more than one window (GLX windows) at the same time, in
which
case the textures are incorrect and I get the following error message:
Couldn't alloc placeholder sz 40000 ofs 180000
Memory heap 0x828db90:
Offset:00000000, Size:00040000, U.
...
I tracked the message down to the function mgaTexturesGone in the file:
redhat-mesa-3.4.2/xc/lib/GL/mesa/src/drv/mga/mgatexmem.c
I am trying to determine whether the problem is:
1) Improper use of OpenGL
2) Exceeding limits of framebuffer memory or some other allocation limit
3) Bug in DRI
4) other
Does anyone have any ideas about this problem?
Here is my configuration:
RedHat Linux 7.2, Linux kernel 2.4.7-10
XFree86-4.1.0
XFree86-4.1.0-0.99.3-GLonly
redhat-mesa-3.4.2
Dual CPU AMD Athlon (running in uniprocessor mode due to DRI problems)
Matrox G450
