That's not a GTK3 build, though, right?

Seems like it uses the same background color as the GTK3 build (the 
current one)? And that is probably the color of the window background.

My current GTK theme has a bit darker windows, so the background color 
looks like fine here, FWIW.

But the screenshot exhibits another (definite) bug: when Emacs is just 
started, the cursor shape is hollow. Switch away from its window and 
then back: the cursor is now filled.
