Dragging the scrollbar thumb when another tab refreshes it's files/view in the background will interrupt the scrolling as if the mouse button was let go, when it was not.
To test...
The tab being scrolled needs to be in Details or Power mode
Make sure below is ticked (disabling this stops the scroll interruptions)
Preferences / Folder Tabs / Options
[X] Process file changes in the background
When interruptions are occuring:
uncheck, Process file changes in the background, click apply
check, Process file changes in the background, click ok
At this point the interruptions will stop, but will reactivate once you view the tab that is being updating in background again.
