[GtkGLExt] display lists sharing problem with texturing enabled



Hi,

I have too problems with gtkglextmm.

1) The gtkglextmm widget is not invalidated (redrawn) if the size of the
gtkglextmm area is too small. I use this instruction (from the
gtkglextmm examples): get_window()->invalidate_rect(get_allocation(),
false);

2) I have multiple gtkglextmm widgets that share the same display lists
and textures. In fact, textures are compiled in display lists so that I
only call display lists to draw the scene. All work fine, but if I
enable texturing and at the time I am switching to the view where the
display lists were initialized, I get the following message in the console:

End of memory blocks

No segmentation fault happens and the program just goes on. Note that
this problem does not occur if I disable texturing.

Any ideas ?

Thanks in advance,

Florent Teichteil.
