The background color of the buttons disappears (updating from 7.9.9 to 8.0.0)

After updating from version 7.9.9 to 8.00, if you open a project and you save an existing window, the background color of the buttons disappears.
In addition, the property “background 3d” no longer exists !!!.
You can see it in this video:

This is the same issue as [BUG-13907] Button's Properties change after updating - we’ll update that topic when its been fixed.
