I have used code from this example - https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/AngularJS/editing-using-contextmenu - to create a context menu.

Occasionally the menu will close immediately after it is displayed, so all you see is a flash of the menu. This has only happened on Chrome on Windows 10. 

It only happens very occasionally, I cannot recreate it at will.

Pressing F5 does not fix it. Only restarting Chrome seems to fix the issue.

See attached video which shows menu 'flashing' for a moment,

 

Hello Gray,

Thank you for the video prepared.

In order to be able to troubleshoot the issue described, we will first need to reproduce it locally. Therefore, I would like to ask you whether you could reproduce the problem reported on the exact sample from our documentation. If yes, could you, please, list the steps required to force the erroneous behaviour?

If the issue could not be reproduced on the above Dojo, can you prepare and send us an isolated runnable sample revealing the problem? Also, share with us any other information about the environment in which the issue could be observed.

Looking forward to hearing from you.

Regards,
Veselin Tsvetanov
