Describe the bug
First of all, great mod!

Attacking with a shield equipped (whether offhand is rendered during attacks or not) randomly results in an annoying model flicker. I linked a video of the issue and it appears to be either the third person model randomly deciding to also render at the same time as the first person model or a very sudden transition on the last frame of the attack animation to the first-person model. Additionally, as you can see in the video, this doesn't happen on every attack.

This is particularly jarring with shields because it occurs even when offhand item animations are disabled, suggesting this is a bug. I'm linking a video of the issue, as well as a screenshot of the problem frame.

To Reproduce
Steps to reproduce the behavior:

1. Go into a world
2. Equip a one-handed weapon and an offhand item, preferably a bulky one, like a shield.
3. Attack with weapon for a while until the glitch occurs (should occur within the first 2-3 attacks)

This is reproducible with just Better Combat and its dependencies and no other mods.

Expected behavior
No distracting animation glitches.

Screenshots or video recordings
Link to an imgur video of the issue.

One of the problem frames.

Additional context
Also occurs on 1.19.2 Forge.

I am unable to improve this further, I don't know any technical solution.
