WGL_ARB_buffer_region doesn't work well on recent catalyst drivers.

Question asked by maytree on Jun 25, 2013

After I save buffer using wglSaveBufferRegionARB() and restore it using wglRestoreBufferRegionARB(), restored buffer has weird value.

 

For example in my code attached,

 

fmin fmax is 1.00000000 before wglRestoreBufferRegionARB() (line 62), and is 0.0039061906 after wglRestoreBufferRegionARB() (line 82).

 

Please help me. Thank you.
