Hello, Mark,
The next official release R2 2020 is scheduled for the first part of May.
Meanwhile, feel free to use LIB 2020.1.423 where the fix was introduced. The following help article demonstrates how to get latest internal versions from your account: https://docs.telerik.com/devtools/winforms/installation-and-upgrades/latest-internal-builds

Can you let us know when the new version will be out that fixes this issue with the RadPanel showing transparent at unexpected times?
