Arrow keys keep on speeding through images without touching

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.

I have been having the same issue now since about june of this year on my M1 Max Macbook pro, with lightroom classic. ive udpated the OS to the current macos tahoe 26.1 and LRC is currently 15.0.1 updated to the most current and also have this same issue. if i hold down the arrow keys in one direction or another ts speeds up and keeps going well after i let go and will contineue to go til hudnreds of photos later or end of strip. 

i have tried this on a new library and catalog and still is occurring as well. 

Presumably your new Mac is a faster machine than your old one and perhaps with a newer OS.  When you hold down a key (rather than just momentarily clicking it), it sends repeateded "key click" commands to the OS over and over till you let go of the button.   Open a text field or document and hold down the "a" key and you'll see a whole row of A's show up.   On your old machine the pace of these repeats was slower and perhaps the keyboard buffer in the machine was smaller so it didn't scroll as far as it processed the queue of those repeated arrow commands.  On the new computer rather than, say, getting 5 repeats per second perhaps you are now getting 100 per second and rather than being able to queue up 20 keystrokes 'to get to' it can now queue up, say, 100 (made up numbers to illustrate point)

If you only want it to go a little ways, don't hold down the arrow key, but rather click it multiple times.
