Possible Match Errors

Possible Match Errors

When glXMakeCurrentReadSGI() associates two GLX drawables with a single GLX context, a BadMatch X protocol error is generated if either drawable was not created with the same X screen and visual as the context.

The color, depth, stencil, and accumulation buffers of the two drawables don't need to match. Certain implementations may impose additional constraints. For example, the current RealityEngine implementation requires that the color component resolution of both drawables is the same.
