I've just upgraded an X86_64 box from Fedora 8 to 10.
fglrx is now 8.58.2
I have an openGL application that used to work fine but now has two problems. I'm using gtkglext-1.2.0
1) Double buffering no longer seems to work.
Despite using
glconfig = gdk_gl_config_new_by_mode(GDK_GL_MODE_RGB | GDK_GL_MODE_DEPTH
| GDK_GL_MODE_DOUBLE);
a call to gdk_gl_drawable_is_double_buffered() returns FLASE.
I use "unique colour" picking, and without double buffering the scene drawn for picking is appearing on the display!
2) I can only open one openGL application at a time, the second one hangs without opening it's window and using 100% CPU.
Any help appreciated.
