I am having trouble getting a virtual scroll running properly. I have data that is very much dynamic within its size. There can be 1 or around 600000 entries that I want to display. Sadly I am having trouble getting something running properly. I forked the dynamic example from the docs.
When setting the entries to around 1000 the scroll works, but when increasing the amount of entries to 1000000 I can't scroll to the bottom and only see around 400000 entries. Playing around with the estimateSize property fixes the issue, but when scrolling the scroll behaviour is weird and jumps in big chunks.
When the count of rows changes drastically, the virtual-scroll should be able to handle both cases without having to change the config programmatically.

Angular virtual dynamic measuring not working right
Angular virtual dynamic measuring not working properly

Thanks for trying out Angular Virtual! The issue you're running into is a hard limit set by the browser. With 999999 items at 120px you're at a total of ~120M, which is well over Chrome's maximum of ~33M (the max differs by browser, version, etc.).
Here's the height style and the actual height that I see on my machine on your StackBlitz reproduction:
Also see #460 for discussion of a workaround. If it works, it would be nice to have a workaround implemented in TanStack Virtual core, but I think it would be possible to implement in userland as well.
