15.04 Beta 1 | Changing theme doesn't work

[Senpos]

Attempts to change theme in "System - > Control Center -> Appearance" are doing nothing. When i click on any theme, the first one, "Custom", changes only (Preview), but system still looks like before. "Customize..." button same as other stuff, don't wanna replace any window borders, theme and so on.

Here is the GIF where i'm trying to explain problem:

I've tried to play around this problem and while Compiz is selected as Window Manager - all works fine, but while Macro is - problem keeps reproducing.
