I have a MFC SDI application created and added CDialogBar to set as main toolbar as you look in the screenshot I attached. It works well on every windows os(Xp, 7, 8, 8.1, 10) of windows tablet devices except only Microsoft Surface.
Please look at this screenshot. the CDialogBar menu is cut off. I don't know reason why this happens. The drawing issue always only occurs on Microsoft Surface 3 which has high resolution and high DPI screen and it works good on any other tablet. This is very strange issue so I dragged toolbar(CDialogBar) and dropped down on any place then the toolbar was re-painted clearly. So.. through this issue, I am sure that this is re-drawing issue. Is there any drawing function to redraw that area?
I am attaching my minimized source code to represent drawing issue.

Please help me. Thanks
Operating System: Windows 10
Tablet: Microsoft Surface 3
Tool: Visual Studio 2015 Update 3
DPI rate: 150%
What I have tried:
To resolve this issue, I have been trying to set DPI Awareness property to None, but the graphics Interface was not good and they were all stretched. I really don't like this solution, I have to find other solution without setting DPI Awareness to "None".
