We found a critical issue in build 5.20201.663 where FlexGrid was flickering when scrolled on iOS 13. We have fixed this issue as of build 5.20201.664. Please update to use the latest version of wijmo to ensure your applications run smoothly on iOS 13.

Build 5.20201.664 is available on NPM, CDN and to download from our website.

If you aren't able to quickly upgrade, you can alternatively add this CSS patch to your application:

.wj-flexgrid [wj-part=root] {
  -webkit-overflow-scrolling: touch;
}
