happening to my launcherpro too. gonna try pete's kernel now.
I sent an email to Ander asking for some advice for these redraws. Here iswhat he said:
I have a five screen setup and I was getting FCs when I tried to access the 4D app drawer. What I did was turn off animations in GB and in the launcher, I turned off the wallpaper hackand the animations for the app drawer. It seems to have helped.The persistence option has been removed from the GB system, so forget about it. About the redraws, It's the normal behaviour when you are running other high memory applications (like browser, youtube, etc) that android system kills other apps to free up some memory. So when you "reopen" the launcher it needs to start from scratch. Usually if you set the launcher as "default", android tries to not kill it (but sometimes it needs to, so there are chances you get "reloads" at some points).
Anyways, using less widgets and less "heavy" themes make the launcher to reload faster and avoiding heavy widgets and scrollable ones will help with "lag".

I've used Slayher and Raidzero kernels and have had very good luck with re-draws, they are exceedingly rare and quick.
My LP Plus settings:
Memory Usage Preset: Light
Use homescreen caches: Yes
Cache Type: Normal
Build caches as needed: Yes
Clear caches on exit: No
Prevent force-closes: Yes
And of course the local.prop re-draw remedy.
