Oddly Invisible; gtk3-git rendering problem?

With gtk3{,-git}{,-ubuntu}: Some things are oddly invisible.

This isn't a functionality problem. Everything works as well as ever; it's even kind of cool, depending on which component gets blanked out.

Case in point: gnome-control-panel keyboard's backmost background layer is stylishly invisible.... but why?

Not so cool: sometimes slingshot-launcher's background is invisible.

In openbox, without a compositor the same oddly invisible areas are black, but videos playing in  vlc show through them. With a compositor (compton) the areas are invisible just as they are in compiz.

*Unfortunately gnome-screenshot doesn't capture the video showing through the black area; note the right corner of vlc's window decoration sticking out from behind slingshot-launcher.

Anyone else find things oddly invisible with gtk 3.14?

This may be related to the opening part of this thread:

That thread has drifted like crazy though. There is good information throughout it.

if you're using anything -git, especially with a big component like gtk+ and on the beginning of development cycle, you shouldn't be surprised if it doesn't work properly.

I've seen the new in-window decorations; actually come to like them in Pantheon 3D (easy to prevent original, redundant decorations; elementary project has also been considering alternatives to window-decoration).
I don't think adding transparency to certain background layers or the color black is part of Gnome's plans, however their plans have been at least half-mad ever since gtk2 was deprecated...

Indeed, not surprised; just curious.
At least, all of the applications displaying the odd transparency actually do work.
