Green flicker haze glitch on moving shapes in After Effects V25.6.0

I am having a green flickering and gllitching issue in After Effects which I have not had previously. I have attached an example - just moving a shape using the position tool sometimes creates a green flash/glitch. I am not using any video assets, just moving PNGs and shapes/masks with position keyframing. I have attached an example - it may be hard to see on first view but at it's worst from 00:01-00:02 and 0:11 - 0:13 and can be seen clearly when slowed down or dragging through the keyframes. I ahve also attached my composition settings.

It appears on the actual composition working file, not just after exporting it. I have tried the following from similar threads from years ago and none have worked so far:

- Disabled both "display > hardware accelerated decoding" and "import > hardware accelerate composition layer and footage panels"
- Switched between Mercury Software Only and Mercury GPU acceleration (metal)
- Purged all my caches

- Restarted my laptop and after effects

- Updated to latest after effects version and latest macbook update
- Changing the composition frame rate

- Tried the file on a different macbook with these specs and also didnt work

Hopefully someone can help - all the other threads are very old or are fixed by disabling the settings above but it's not working for me 😞 Thank you!
