The user interface is too small or too big for my screen resolution.Since version 2.1.0 there is a native option built into the plugin to scale the user interface (for Windows only). Open the Settings page and go to the section UI SCALE. Here you can decrease or increase the scaling.
If you use this option, make sure that the scaling option, which your host might offer for scaling plugins, is disabled, since it might cause conflicts, and our native solution usually works better than the ones from the hosts.
If that is not working for you and you are using the DAW Reaper, the following article from the time when Reaper 6 was released describes various solutions to that problem. Also have a look at the comments section.
