It seems to happen most frequently if I have multiple ChanEQ or Multimeter panels open displaying live spectrum analyzers. Unfortunately, that's something I need a lot of the time when mixing/mastering...

Sounds like Lion's new graphics system is taxing the Mini's GPU. The fact that it shows up when the graphic metering windows are open is telling.
What does Activity Monitor show being used?

This was actually happening somewhat in SL too, but it's way worse in Lion.
Activity monitor doesn't show anything as using a large amount of CPU. It also doesn't feel like a GPU strain - everything on the screen is updating completely fluidly and so on, but it seems like there's just a problem with how events are being processed in the app itself. Like they're using a timer to update the meters that's overriding the input event queue or something.

I have the same problem UI is extremaly laggy with all plugins. I've the last MacPro 8 cores, 6gb ram and a faster HD. The monitor activity show always less than 20% but i have the problem when Logic is running small & larger projects. Any solution?

i have the same problem here ( mac pro late 2008 2 ghz ) / Lion 10.7.2 / Logic 9.1.5 / 9.1.6.
Using more than 4 tracks or some spectrum analyzers or other complex plugins makes logic nearly unusable. the response time to mouse events gains to 2-10 seconds. The tip from ( https://discussions.apple.com/thread/3226612?start=0&tstart=0 , just switch shortly to exposee, klick on Logic again), seems to help very good, but only for the next mouseaction. Then everthing is laggy again. Grrrrr ! Come on Apple ! Fix this ! And do it fast ! There is definitely something wrong with the event handling queue in Lion i guess. The same version of logic ( 9.1.5 ) worked without any problems under Snow Leo.
kind regards from germany

Same problem here. Gets to be unresponisive/slow. I wonder if it has anything to do with a dual-monitor setup? Only thing I can think of. Anybody else?
Login 9.1.6 and Lion (latest).

Okay. Unplugging the second monitor (iMac 2.4 Core 2 Duo) seemed to fix this maddening problem. Hopefully it's a Lion bug and not a hardware limitation. I will miss the extra screen real estate, but I won't miss this terribly laggy interface.

I posted this originally on Mac Pro Help, but I thought it would be helpful here too!....
Same problem here with Lion. I'm on a Mac Pro 2.6 quad.
I have another Mac Pro tower I use for video and graphic design, and since the issue seems to be GUI related and not processor related (Logic's CPU meter is never peaking), I swapped out the video card from my video machine into my Logic machine. I removed the GeForce 7300 GT and replaced it with my ATI Radeon X1900 XT ...and, NO MORE Slow downs!
The problem seems to be video card related, and at least in my case, specifically the GeForce 7300 GT. Hopefully Apple will read this and fix this issue. Until they do, try a video card upgrade. I don't think they make the X1900 any more, but there are faster/better ones available now anyway. I'm sure this will continue to pop up as more and more Mac Pro owners take the jump and upgrade to Lion.

Of course, and Darren's answer points out that Pro users have a quick fix in that they can change their GPU while waiting for Apple to remember that non-GarageBand users exist. Integrated graphics users, not so much.

I also didn't have any issues on Snow Leopard with my Mac Pro's original GeForce 7300 GT. The X1900 I swapped into my Logic Mac Pro has 512 megs of VRAM ...the old card only had 256. I doubt it's the driver, but possibly related to Lion's graphic system requiring a stronger video card . Hopefully not. BTW, I forgot to mention that I'm using two displays also.
Just to assure everyone, I swapped the card on Saturday and I've used Logic non-stop since then. It seems that the vid card swap out alleviated the problem 100%.
