Phantom disk spikes

I have a 10 core i9 11th gen running Windows 11, all my samples/projects are stored on Samsung EVO NVMe and every time I click on the transport bar or hit Ctrl-B I see a disk spike happen - it hits red but doesn’t stay red.

To recreate - open fresh project, all is fine. Add any audio track at all, and afterward clicking anywhere in the transport measure to change project position will cause a disk spike.

Windows performance monitor shows no activity so I think it’s just cosmetic.
