Window not moving smoothly

Hello,

I'd like to report a problem with the window component. It's only related to Google Chrome and occurred after the last Chrome update. Windows and Mac alike.

When dragging a non-modal window it does not move smoothly, but in a jerking manner. There is no problem with modal windows.

I've enclosed a screen video. The first windows is moving perfectly, the second erratically. Of course, this is not a major issue, but the client still complains.

This is the configuration. .Draggable(true) does not change the behavior.
@(Html.Kendo().Window()
      .Deferred()
      .Name("insert-products-window")
      .Title("Placering produktdokument")
      .LoadContentFrom("LoadInsertProductsDialog", "Catalog")
      .Events(e => e.Error("utilities.handleWindowError"))
      .Events(e => e.Close("insertProducts.onClose"))
      .Events(e => e.Activate("insertProducts.wireToolbarEvents"))
      .HtmlAttributes(new {style = "padding: 0;"})
      .Scrollable(false)
      .Draggable(d => d.Containment(Model.IsPhone ? "" : ".body-content"))
      .Modal(false)
      .Width(Model.IsPhone ? 0 : 700)
      .Height(Model.IsPhone ? 0 : 450)
      .Resizable(r => r.MinWidth(300))
      .Resizable(r => r.MinHeight(260))
      .Visible(false)
      .Actions(a => a.Custom("help").Minimize().Close())
      )

Hi Peter,

This issue was related to a Chrome-specific regression reported in 2019. The Window component has since received drag performance improvements and currently uses CSS transforms when moving the window.

We are unable to reproduce the reported behavior with the current implementation. We are closing this item as outdated and no longer reproducible.

Regards,

Hello, Peter,

We were able to replicate the reported issue and indeed it seems like there is an issue introduced with the new version of Chrome. This is why, I have converted this thread to a bug report, and I have updated your Telerik Points for reporting it.
