Spaghetti Arms Rig problem

Hey guys. Having a big issue with my rig and it’s arm IK I believe?

The arms are spaghetti formed.

It happens whenever I click through Rest Pose and Pose Pose.

It’s deformed but when ever I click a frame it usually straightens back together.

I had this problem before but I dont know how it was fixed. I think it has something to do with The IK’s or Copy Parent Bone’s rotation.

Here are an Example.

I know it doesn’t effect the render.

But when cycling through animations to see how smooth my animation is functioning. it can get very irritating to the point where I dont know what is actually a problem and what isn’t.

It’s basically unprofessional. And I’d really like to cut it out.
