Performance worsening in R3 release?

Hello,

after upgrading my Gantt chart to release 2020 R3 SP1 I noticed a significant performance drop in the chart to the point of it not being snappy enough to give to end users. I have made a simple repro at https://dojo.telerik.com/OjOCEjIm/4 (I hope this links to my custom edit, if not the code is down below to copy paste into a Dojo window). It is a simple Gantt chart where I add 50 summary tasks and 50 child tasks for those.

When running the chart in the dojo under 2020 R2 SP1 the chart loads fast and clicking open a summary task has an almost imperceptible delay. But when switching to 2020 R3 or R3 SP1 releases from the dropdown in the top left, the same chart takes multiple seconds to load and opening of a summary task takes about 1-2 seconds.

I'm in a situation where the data to be displayed in the Gantt sometimes is in the order of 35-50*35-50 tasks. Are there any performance hints I might employ to make the R3 release usable as I would like to use for example the columnMenu option that I believe is only available in R3? Also any and all performance hints are welcome.

If the link up doesn't link to the custom Dojo, here is the code to copypaste:

Inline multiselect?

Currently the multiselect widget gets wrapped in a div, causing it to move to a newline. Other similar widgets like the dropdownlist do not. Is there a way I can make the multiselect widget not move to a newline?

I tried setting the display to be 'inline-block', but then it shifted the multiselect to be 'hovering' above the available data.

Custom view broken in 2020 R3 update?

Hello,

to me it seems the 2020 R3 update breaks a little on (some) custom views. I have a custom view adopted from your documentation at https://docs.telerik.com/kendo-ui/controls/scheduling/gantt/how-to/creating-custom-view. If I open this in the Dojo, the tasks don't line up with the table (see attached file). If I change back to 2020 R2 SP1 release from the dropdown at the top left (and cleanup the stylesheet reference), the tasks once again lineup with the table.

Also the line this.list.header.find("tr").height(height + "em"); that seems to be used to adjust the tasks <> tables gives an error of Uncaught TypeError: Cannot read property 'header' of undefined when I update to the latest release and am running the Gantt in a node.js app. Where can I do the adjusting in a custom view when I update to the latest release?

Grid not working on mobile/tablet devices in 2020.3.1021

Hi,

I updated my project to Kendo UI for jQuery 2020.3.1021 but then all grids stop working on mobile or tablet devices. When downgrading to 2020.3.930 grid works fine.

I have tested on iPad,iPad Pro, Samsung S10.

Easiest way to reproduce the error is to open the demo page here: https://demos.telerik.com/kendo-ui/grid/index in Chrome on a pc and emulate an iPad for ex. Or load that

In the browser console you can see the javascript error: "Cannot read property 'rows' of null".
