UI when being moved lags heavily

Things I have tried

I’ve gone through all of the settings available and made modifications of the enabled/disabled options. The applications works fine. But, when I click-and-drag the interface, it lags heavily.

Unsure why; it doesn’t seem to be a settings’ issue.

I’m trying to determine a fix.
