I've confirmed (after simon asked on Mattermost) that this is a regression that happened between 1.4.1 and 1.5.0, and also exists on 1.5.1.
This can be seen in the test case posted at https://github.com/slint-ui/slint/files/14938821/my-project.zip by changing the slint dependency to "= 1.4.1" or "= 1.5.0", and changing the row count to 1000.
In 1.4.1 using the mouse wheel to scroll the list (or dragging the thumb) is smooth. In 1.5.0+ there are big jumps in lag, beachball timeouts, FPS = 0, etc.
Discussed with simon here: https://chat.slint.dev/public/pl/a8jn76pua3nr8xdbq8q49dasww
