Hi team again,
The expand button becomes oval and shrunk in high DPI. It scales correctly in the default theme, but incorrectly in other themes - I tested Crystal/Material/Fluent and neither worked. Please see ss attached for your reference.
Thanks a lot.
I have logged it in our feedback portal by creating a public thread on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.
I have also updated your Telerik points.
Currently, the possible solution that I can suggest is to specify minimum size for the button:
Me.RadCollapsiblePanel1.CollapsiblePanelElement.HeaderElement.HeaderButtonElement.MinSize = New Size(30, 30)
