UI Glitch
All of my plugins (except for PRO-Q4) are exhibiting the same glitch where the animations don't show up but you can hear that the plugins are still actively processing. On the DS for instance, you can audibly hear the DS'ing but the UI shows nothing as if the plugin is bypassed. This is happening for all my plugins but the Q4. I redownloaded the total package but that hasn't helped.

I'm seeing this too now.
Not sure what triggered it, either must have been a macos update or a logix pro x update.
Not an exhaustative list, but as you say, Q4 is fine, but Pro-DS is not, probably others too.
This might be not be related, but I'm also getting severe lag on my midi input now (well, specifically, the midi input is fine, I tried another program to check and can see the midi activity in Logicx), but the time it takes for logic to generate the audio from Twin3 is long.
I might try removing all the broken FF plugins and see if that fixes it, as maybe they're reporting something bad back to logic that is upsetting things.
Ok, another update:
The lag was something else, a plugin I'd added on a channel stack, so that was a red herring.
Timeless 3 has the problem also.
L2 too, interestingly, that one's drawing a solid mid-blue line in the centre of the visualiser, so I'm guessing that's what usually draws the output, just it's not getting any audio for some reason perhaps?
