Pro MB scaling stuck

I can not access any of the controls inside of the Pro MB plugin because of the scaling is stuck, or something. Is there a way to rest this?
I tried reinstalling the plugin and it did not help.

Hi Chad,

Could you try entering the command below in Terminal:

defaults write com.fabfilter.Pro-MB.1 ScalingAdjustments ""

Ah! That worked.

Does FabFilter know why this sometimes happens? In my DAW I can hover my mouse over the Resize button when I’m at 100% scaling and I can even see the help-tip bubble pop up, but clicking it does nothing.

Even at 200% scaling I notice that I have to get the mouse riiiiight up in the upper left corner of the Resize button before I can open that menu…

cheers,

That may have to do with a bug in Logic on Tahoe where the bottom part of the plugin cannot be clicked. We've reported this to Apple but so far they haven't fixed it, unfortunately.

Cheers,

This isn't just a Logic bug, this happens in Reaper too. Changing the % scale resizes the UI, which is not reversible.

Wild that you can break the plugin via in-UI options. Fix this please, these plugins aren't cheap.

We're currently testing a fix, we hope to release a general update soon.
