fwiw, we have that patch as well..  the issue is not an egl/gl error,
but it happens by chance.  Ie. it requires the egl surface to be
destroyed, and then re-allocated as a different type (such as from
pbuffer to window), and get the idential pointer address as the
previous surface.

In other words, I think the cases where it is working is only by luck.
