3 months ago Given that this is a pure temporary visual glitch and the dropping Firefox percentage, I'm unlikely to look into that. Feel free to investigate and submit a PR.
P.S. It's not that I dislike Firefox in anyway, but my capacity is limited and I can't prioritize it.
Description
I'm using Virtuoso Grid in my project to display a grid (20x60 with up to 20M items, each item has a small value) and it works well if I navigate the grid using the mouse scroll wheel. It is fast and responsive. But, in Firefox, if I drag the scrollbar, in fast movements or bigger jumps, the grid blinks (all grid is gone) and then it renders all the elements.
Reproduction
It is possible to test here: https://virtuoso.dev/grid-responsive-columns/ Just increase the value of totalCount, and adjust width and padding of Item and ItemWrapper, so you display more items.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
Just do the same using Chromium and Edge. It works well, as intended.
