Lag when people join/leave raid

[secutanudu]

I had this problem with CT Raid Assist when 2.0 first came out where the screen qould quickly glitch every time someone joined or left my raid group.

I'm not sure which mod is doing it, but the problem has returned. I've tried disabling mods to no avail. Has anyone experienced this lately?

I have a fast dual-core machine with tons of ram, so i dont think its a problem with my pc.

Some of my most recent addons include Grid, PerfectRaid, X-perl unitframes. I have way too many addons to list them all here though

Any help or advice would be great. Thanks.
