My mistake. I had a rebased branch with one extra commit that I used for
bisecting and forgot to change to master before doing this.

I did. And it seems I forgot to mention in the commit message that this
patch does not regress the bug solved in said commit, it just, IMO, a
better fix for the problem.

What I'm trying to do here is have the opaque region of the simple-egl
surface set properly when it is run with the -o switch, even when not
running fullscreen. That setup uncovered a bug where too much redrawing
was culled when using overlays.
I guess I created this whole mess because when I added fullscreen
support I made it use an XRGB config to test the scanning out of client
buffers. The "if (fullscreen) opaque = 1;" conditional survived this
far, but since the introduction of '-o' it shouldn't be needed anymore.
(Well, the compositor should know that a fullscreen surface is opaque
anyway, but that's a different story.)
So what this patch does is:
- reverts your patch;
- removes the if fullscreen make the window opaque switch, which fixes
the problem of getting an opaque window if simple-egl is launched with
-f and later made not fullscreen;
- sets the opaque region in redraw() also when in fullscreen mode,
regardless of the -o switch, so the compositor still scans out the
client buffers in that case.
Anyway, I'll resend the patch with the correct sha1 of the commit and
try to be clearer about what the patch does.
