Adding a line here https://github.com/petyosi/react-virtuoso/blob/master/src/scrollToIndexSystem.ts#L93 that says top += 1000
fixes my use case, but obviously that's not a real solution.
If you're going to build a chat interface, I strongly recommend the MessageList component. It covers a bunch of specifics for that particular UI.
As per the problem you experience - please check the troubleshooting section of the docs.
I did look at MessageList but as my app is open source, I cannot use it.
Thanks for the pointer, I don't know how I missed this particular troubleshooting section. How embarassing. I removed margin from the outer element and it is working now. thanks so much.
Describe the bug
Setting
<Virtuoso followOutput={true} alignToBottom={true} startReached={onYReachStart} firstItemIndex={Number.MAX_SAFE_INTEGER - currentMessages.length} data={currentMessages} itemContent={...} />
adding new items when scrolled to the bottom does scroll down, but often leaves some px away from the bottom that is not scrolled to.Reproduction https://codesandbox.io/p/sandbox/intelligent-dawn-cn35dz?layout=%257B%2522sidebarPanel%2522%253A%2522EXPLORER%2522%252C%2522rootPanelGroup%2522%253A%257B%2522direction%2522%253A%2522horizontal%2522%252C%2522contentType%2522%253A%2522UNKNOWN%2522%252C%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522id%2522%253A%2522ROOT_LAYOUT%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522contentType%2522%253A%2522UNKNOWN%2522%252C%2522direction%2522%253A%2522vertical%2522%252C%2522id%2522%253A%2522clxv2ds2a00062066grxd1p6n%2522%252C%2522sizes%2522%253A%255B100%252C0%255D%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522contentType%2522%253A%2522EDITOR%2522%252C%2522direction%2522%253A%2522horizontal%2522%252C%2522id%2522%253A%2522EDITOR%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL%2522%252C%2522contentType%2522%253A%2522EDITOR%2522%252C%2522id%2522%253A%2522clxv2ds2a0002206600g5clyq%2522%257D%255D%257D%252C%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522contentType%2522%253A%2522SHELLS%2522%252C%2522direction%2522%253A%2522horizontal%2522%252C%2522id%2522%253A%2522SHELLS%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL%2522%252C%2522contentType%2522%253A%2522SHELLS%2522%252C%2522id%2522%253A%2522clxv2ds2a000320666a2pqukk%2522%257D%255D%252C%2522sizes%2522%253A%255B100%255D%257D%255D%257D%252C%257B%2522type%2522%253A%2522PANEL_GROUP%2522%252C%2522contentType%2522%253A%2522DEVTOOLS%2522%252C%2522direction%2522%253A%2522vertical%2522%252C%2522id%2522%253A%2522DEVTOOLS%2522%252C%2522panels%2522%253A%255B%257B%2522type%2522%253A%2522PANEL%2522%252C%2522contentType%2522%253A%2522DEVTOOLS%2522%252C%2522id%2522%253A%2522clxv2ds2a00052066l4b2byqr%2522%257D%255D%252C%2522sizes%2522%253A%255B100%255D%257D%255D%252C%2522sizes%2522%253A%255B50%252C50%255D%257D%252C%2522tabbedPanels%2522%253A%257B%2522clxv2ds2a0002206600g5clyq%2522%253A%257B%2522tabs%2522%253A%255B%257B%2522id%2522%253A%2522clxv2ds2a00012066qs830qb7%2522%252C%2522mode%2522%253A%2522permanent%2522%252C%2522type%2522%253A%2522FILE%2522%252C%2522filepath%2522%253A%2522%252Fsrc%252Findex.tsx%2522%257D%255D%252C%2522id%2522%253A%2522clxv2ds2a0002206600g5clyq%2522%252C%2522activeTabId%2522%253A%2522clxv2ds2a00012066qs830qb7%2522%257D%252C%2522clxv2ds2a00052066l4b2byqr%2522%253A%257B%2522tabs%2522%253A%255B%257B%2522id%2522%253A%2522clxv2ds2a00042066qavivrve%2522%252C%2522mode%2522%253A%2522permanent%2522%252C%2522type%2522%253A%2522UNASSIGNED_PORT%2522%252C%2522port%2522%253A0%252C%2522path%2522%253A%2522%252F%2522%257D%255D%252C%2522id%2522%253A%2522clxv2ds2a00052066l4b2byqr%2522%252C%2522activeTabId%2522%253A%2522clxv2ds2a00042066qavivrve%2522%257D%252C%2522clxv2ds2a000320666a2pqukk%2522%253A%257B%2522tabs%2522%253A%255B%255D%252C%2522id%2522%253A%2522clxv2ds2a000320666a2pqukk%2522%257D%257D%252C%2522showDevtools%2522%253Atrue%252C%2522showShells%2522%253Afalse%252C%2522showSidebar%2522%253Atrue%252C%2522sidebarPanelSize%2522%253A15%257D
