Hi Henri,
I know what you said about disabling the warning but that would not actually prevent the viewer from crashing if it is really out of memory -- at least I assume that suppressing the warnings won't actually prevent crashes!

The issue I'm mostly concerned with is why the Legacy version seems to work just fine in terms of memory management while the Stable version does not. In other words, Legacy is 'stable', and Stable is not. They're handling memory differently and the older one works better.
This is even more important in light of your recent announcement that the Legacy version would go into a maintenance-only mode after server-side baking is implemented by LL.
So, I am hoping that whatever is not working right in Stable can be fixed, and i am offering to help with testing or gathering logs or however I can. I appreciate that you don't have a mac, my offer is for both yourself and Katherine (and anyone else who might be looking into this.)
Cheers!
