[Paraview] Rendering Slow Down on OS X, ParaView CVS, Custom GUI Plugin

[Mike Jackson]

System: OS X, 10.4.11, Intel, 2 GB Ram, Xcode 2.5, ParaView CVS from  
this morning.

Generally rendering was fine until I loaded one of my plugins and  
applied the filter that the plugin contains. The plugin also has a  
custom GUI that is loaded and I created a new Menu Category for the  
filter. Selecting the filter from the menu, clicking "Apply" and then  
trying to rotate/render the scene becomes very slow. Deleting the  
filter returns the speed to normal. Also, NOT loading the Client Side  
plugin BUT applying the same filter results in NO slow down.

I ran "Shark" against ParaView 3 while interacting with the render  
view (constant rotation by click-dragging in the render view) and I  
found that the time is being spent in the following call:

15.1 s	16.1 s	libpqComponents.dylib  
pqFiltersMenuManager::updateEnableState()	

That is 15 seconds out of a 30 second sample. ouch.

Here is the entire stack up to that point:

I just noticed this today but the last time I checked anything like  
this was a few weeks back. Has anyone else seen something like this?
