@d9nny i'm happy you find the library useful. |
Here's one i did trying to track down why touch events fired on wrong locations after including ngx-popper. It didn't end up reproducing my issue, but it does do bad things to FPS while scrolling after opening and closing ever more tooltips. |

Hi,
Thanks for the wrapper, it's great.
I'm having a bad performance issue when scrolling in an ngFor list after multiple dropdown's (using ngx-popper) have been used.
I have a list, each item has a dropdown, which is only added to the DOM if the user is hovering on the item. It works great initially, but as I use more and more of the dropdown's (Only one at a time), the scrolling of the list becomes very laggy. I replaced the dropdown's with ng-bootstrap's dropdown and that solved the issue, so i think the issue is being caused by popper. It's also just happening to the list where the dropdown's are. So if I have two lists and I use the left one heavily, scrolling the left will become very laggy, but the right will be fine.
I'm assuming something is getting left behind, a listener or something? Any ideas what might be causing it?
Thanks
