Description Eric Moffatt CLA 2011-02-28 16:04:42 EST 
We are currently using the 'visible' flag to control which MToolControls (representing minimized stacks) get shown to the user. However, this approach means that all minimized stacks (regardless of the perspective they're in) get renderered on startup.

The obvious fix is to move away from using the 'visible' flag for the MTC's and use the TBR flag instead. This should be OK since the TrimStack is not really that expensive to re-create as needed...

Just checked this with 4.2RC4 and it's not as bad as I had thought. The only parts that get rendered are those in the current perspective's minimized stacks. If you have minimized stacks in other perspectives their parts don't render until the perspective becomes active.

I would argue that this is correct behavior. The views are supposed to act just as if they were being displayed in the presentation so not having them render on startup would result in potentially strange behavior...
Comment 2 Eric Moffatt CLA 2013-10-21 14:53:54 EDT 
As long as it's only the 'selected' item in the minimized stack that gets rendered then this bug should be closed as FIXED.

As per the last comment..
