I seem to have found a temporary workaround.
In your useVirtualizer
you can set overscan
to a relatively high number. This atleasts allows users to scroll that many items before it starts to glitch.
const rowVirtualizer = useVirtualizer({
count: 1000,
getScrollElement: () => scrollWrapper.value,
estimateSize: () => 40,
overscan: 100,
});

So sad workaround 😢 tanstack/virtual api looks great, but because of this error, it is impossible to use
Happening to me too, I've tried to use this library 3 times for the last year and with no luck because of this exact issue
This last try, seems like not setting an overscan works 2/3 of the time
Also, this other workaround seems to work too https://github.com/TanStack/virtual/issues/659

Edit
As described here, this is a working true fix https://github.com/TanStack/virtual/issues/619#issuecomment-1969516091
Describe the bug
This problem occurs when you use smooth scrolling, i.e. via touch screen or trackpad
Using the 'dynamic' version of the scroller and Vue problems occur when you scroll up. Other versions, such as fixed an variable height work fine.
Scrolling down works fine, however, the second you start scrolling up it causes a jittery movement and the rows don't actually scroll up, instead it resets its position. You can hopefully see it clearly in my provided videos. For example: row 53 stays in view.
The problem is most notable by scrolling slowly. By scrolling really fast you can get over it temporarily, but as soon as the scroll starts slowing down, the problem occurs.
This issue occurs in the offical example!

Steps to reproduce
Expected behavior
I expect to be able to smoothly scroll up using the dynamic variant on all platforms.
