egl-winsys: Bind the framebuffer before swapping (2.29 KB, patch)

Description Neil Roberts 2011-12-05 16:18:33 UTC 
The EGL spec says that the surface to be swapped must be bound to the
current context for eglSwapBuffers to work. Here is a patch on top of
the wip/rib/master-next branch that we should probably try to remember
to land along with that branch.

egl-winsys: Bind the framebuffer before swapping

For some reason the EGL spec says that the surface passed to
eglSwapBuffers must be bound as the current surface for the swap to
work. Mesa validates that this is the case and returns an error from
the swap buffers call if not.

Test case

Here's a short test case to show that it really doesn't work without the patch.
