Opening the visualization creates this black box underneath the menu

[vadufl]

Hi, whenever I press the dropdown to open the visualization menu, this black box appears that I can't get rid of unless I close and reopen the app. Is there any way to fix this?

You'll need to remove the existing studio.xnf file (modern skin settings file) from the settings folder (usually in %appdata%\wacup) when wacup is not running & allow it to be re-created the next time you run it. That will reset any skin specific customisations / window positions but is just something the re-used plug-in from 5.666 has a thing for doing.
