I'm looking into the viability of using the WinForms RadSyntaxEditor for a small project.

I think I've come across a bug when it comes to DPI scaling.

The component itself seems to work fine with DPI scaling except for the search/find functionality. When you search for some text and click to go to the first instance it finds, the actual text is off screen, though it is highlighted correctly (when you scroll down you can see it highlighted).

If I set the CaretPosition manually to a line further in the document, it also displays correctly so it seems to be specifically limited to the  built-in Search/Find panel.

This is easy to replicate by changing Windows display scale to anything other than 100%.

Hello, Kevin,

Thank you for reporting this.

I tested it on my end and confirm this is an issue when the monitor scaling is more than 100%.  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 for bringing this behavior to our attention.

Currently, due to the specifics of the issue, I am not able to provide a suitable workaround.

Should you have any other questions or concerns do not hesitate to contact us.
