I don't know how long it could take for a fix but leaving such a problem for almost 2 years makes me think no fix is expected for Resolume 4.....
Please Joris say I'm wrong and that you are planning to fix the stuttering issue for Resolume 4.
Than I don't really care about Resolume 5!!! It can take even 20 years and I'll be fine with Resolume 4.
I look forward to hearing from you.
There are several 4.x updates still planned.
