No need to apologize for the bugs, it's never possible to catch everything, plus different systems as you pointed out with framerate can have bugs that only effect them.
I only mentioned them so that you'd know that they are there. not as any type of complaint.
I will say though for when it comes to recording games right now I am using a dual PC setup so it can be a cause of bugs once in a while. So it is possible they all could just be related to that.
