Hi! I found a few bugs for me.

1. When I load the first time the game, the rotation window is black screen.
2. I play as ret paladin and when I need to use the spenders (templar virdict or divine storm), the rotation window is black. Apparently it does not display correctly. Maybe because the rotation for this class - and spec was not updated for a long time.

Should be fixed by 5a24c52
