I've been dealing with this UI hiccup for a while now and just cant get my head around how to fix it.
I've got a RadRibbonForm with a RadRibbonBar on it (of course)
The theme is VisualStudio2012LightTheme
There's a RadDropDownButtonElement in one of the groups.
I made the surrounding area darker to bring out the contrast in my images.
Here's the problem:
When you look at the enabled button with no action - it looks perfect. You can see this in image_1
When you mouse over though - you can see a little nibblet of pixels above the arrow-button portion - this is image_2
When you mouse down on the arrow the UI bug becomes very noticeable - this is image 3
Any thoughts on how to correct this?
