[Bug 49072] buttons are sometimes colored in a wrong color in the human theme

[Sebastian Brocks]

Public bug reported:

When using the human theme, about 30% of all buttons that are drawn are miscolored like in the screenshot, not only in that brown color, but also in different colors, like light-blue, light-yellow, etc.
I'm using Dapper.
This does not happen with other themes.
