Lightroom Classic phantom/continuous scrolling after latest update

Hi there, since updating my Lightroom Classic to 15.1.1 i now have the dreaded ‘phantom’ scrolling when trying to quickly go through images in my library.

If i go through each image individually, it’s absolutely fine. However if i hold the arrow key for more than a second, it will rapidly scroll through images non-stop and in most cases refuses to stop until it reaches the end.

I’ve looked through previous topics - i’ve tried resetting preferences, clearing cache, disabling GPU and i have no tablets or plugins to worry about interfering. The only thing that is different is i upgraded to Mac Tahoe 26.2; i tried going back to previous versions of Lightroom after this and unfortunately the issue persists.

Can anyone shed any light on what else i can try to clear this issue or a workaround? I do a lot of action photography, so quickly being able to scroll through images in library before development is a massive help vs. simply scrolling image by image.
