Problem with p-virtualScroller

[tim.wilkins]

I'm using this but since upgrading to version 14 rc1 I've been getting weird behaviour: If I have 16 or more items and try to scroll down it keeps adding items back in (i.e. items which have scrolled off the top) so I can never scroll to the bottom. The scrollbar jumps around. In case it depends upon any settings I'll include some of the html:
<p-virtualScroller *ngIf="!CompactDisplay" [value]="appService.selectedQueue?.PrintRuns | jobsFilterPipe : SubstrateTypesFilter : searchFilter" scrollHeight="680px" itemSize="164">
<ng-template let-job pTemplate="item">
I'm fully up-to-date with Angular (14.0.4) and am using Chrome as my browser (103.0.5060.114).

I have the same problem with p-virtualScroller with the jumping. It was working on primeng 12 but when I updated to 14 the jumping started. I tried switching to their p-scroller which did not work, doesn't appear to be finished in 14, no [value] input.

I ended up switching to ngx-virtual-scroller, took just a few minutes, and its working nicely now. Hopefully primeng 15 has this issue fix .

Hi could you explain how you switched from p-table to ngx-virtual-scroller?
thanks

Does anyone have any idea what provokes this bug? I've some apparently similar layouts but it only seems to affect about half of them. At the moment it's more of a problem when using virtual scrolling with p-tables. It's now quite a long time since this was reported and since it's not been fixed I'd like to work-around it if I can (the appendOnly option stops the problem but obviously increases resource usage which is a serious problem for large tables).
