[Chimera-users] Running out of memory when recording movies

[Oliver Clarke]

Also, I've noticed that if I try to record another movie in the same
session of chimera after having recorded one already, I run out of memory
very fast, whereas if I restart chimera and immediately reload the same
session, I am able to record the same movie without a problem - I wonder if
maybe there is a memory leak of some sort?

Cheers,
Oli
