RibbonWindow: Standard window buttons are cut when DPI settings are high
We have a RadRibbonWindow.
When it is run on Windows XP (or on Windows 7, "Windows Classic" theme) and the DPI settings are high (above 170 %), the standard window buttons (Minimize, Restore and Close) are not displayed properly (they are cut). Also there is too much space between them.

Hi, I wanted to chime in and see if there is any plan to still address this?

Microsoft showed a possible solution for this issue in 2018 but alas this is not possible with some of the Telerik WPF controls.

This is especially anoying for us since our application main window inherrits from RadRibbonWindow which blocks further access to PerMonitorDPIWindow


In light of WPF still having a bright future ahead, it would be grand if this could be picked up. High DPI is not an uncommon scenario anymore.


Thank you for any feedback in advance. :)

I'm using Win10, and similar issue. 
As soon as the display scale of the main display is anything other than 100% the window icon is rendered at the wrong size.  Reading the template I understand it binds to Shell.SystemParameters2.Current.SmallIconSize.

Apparently those params are not DPI aware.
Further the IconConverter doesn't extract the (desired) size from a multi image icon. It reads a 16x16 then stretches it to whatever it thinks it ought to be.
