After installing 10.5, I noticed that some FabFilter plugins don’t work as they should.
It is possible to select and load them, but their slot shows as grey instead of blue, with a “volume dial” as icon instead of the bypass icon.
Opening the GUI via double-click or by clicking the “e” icon doesn’t work, also the drop-down menu (down-arrow) doesn’t work anymore. Only way to remove the plugin is to move the active box via cursor keys and press “delete”.
Something is broken in there…
