There seems to be a bug concerning tabs headers of TabControl when used with Office2016 theme.
The color of the header changes from white (active tab) to light blue when a control on this tab is hovered. White background is shown only when mouse hovers only over TabControl Tab panel directly. See gif attached.
Hello Grzegorz,
Thanks for the provided details and the screenshot.
I can confirm that this is a bug on our side. I already brought it up to the development team. The fix will be part of the next LIB, scheduled for the beginning of next week.
For bringing this to our attention, I am updating your Telerik points.
Regards,
