Sorry, no. Just drawing smaller-and-smaller rectangles with color (0, 0, 0,
0.2) does not reproduce this issue. GTK must be doing more than just that and
I'm not prepared to dick into GTK's rendering loop.

Also, the GTK test case "flickers" here, meaning that sometimes I get the
expected content and sometimes the wrong one. So why does GTK redrawing this
thing when I hover over it with the mouse and what is it doing different in
this case?
