Freezing-Bug on UI5-Launchpad

Hello,

we encountered a bug in which the whole website freezes in a certain scenario.
We have embedded the dhtmlscheduler.js library into a custom SAP UI5 (Fiori) Application and it works most of the time.

The freezing occurs when a user launches the app and moves the mouse very quickly to all directions.
We checked the console/network-tab in chrome and it is the dhtmlscheduler-libery which is causing the freeze.

Is this a known issue and is there any bugfix to this problem for today?

Thank you in adavnace
Maxim
