[fixed] Performance

[micheus]

Micheus you that have development tools available, can use observertart() to see where the memory is being used (or lost).

I'm going to find a time to take a look this weekend. Today is a busy day.

Anyway one day I made 80K project left It minimized on my computer and after 2 hours when I came back to work around It was laggy as is`t before

Marcin Maćkowiak, thanks for extra tests.
Yeah, it seems to be related to Face mode only - that is good since we know where to start to look for - and what you have observed would be related to the Auto-Save feature since after save the project I also noticed a small increment of memory - not so huge -, but after 2hours if it's repeated each 10minutes or less...

So, until we discover what is happening it's a good idea keep the auto-save enabled and/or save your project after each important step has been done.
