WowAce

What steps will reproduce the problem?
1. Join any raid and using RAID frames
2. After about 5-10 minutes on in combat FPS drop to under 10
3. FPS comes up some after leaving combat but drops again in combat

What is the expected output? What do you see instead?

What version of the product are you using?
r879

Do you have an error log of what happened?
No error log at this time

Please provide any additional information below.
only way to get around is /reload or disable addon
I've tested that it is caused by Xperl by disabling the addon after the FPS drop and never had the issue
It also massive affects the follow/mission results screen get close 1 fps

This the error post that comes up for x-perl when in a raid and may be what is causing the FPS drop.
