Thanks, but it's off the mark.

The issue is around rendering. The phnomenon is;

> If i move to another virtual desktop, and then return to
> the one with the emacs window, it looks like emacs never gets focus.
> Enlightenment's borders do change colours to indicate it has focus,
> but the cursor remains an empty box instead of a solid rectangle.
> Typing in the window also shows nothing happening. Until... If i
> minimize the window and bring it back, or if i shade and unshade the
> window, it all looks ok again, and everything i typed is there! So i
> can be typing blindly with nothing appearing in the window, then shade
> and unshade, and see that everything i typed (more often than not on
> the wrong line, because i couldn't see it).

Regards.
