We’re experiencing a performance slowdown in our Angular application whenever a tooltip is hovered. Upon inspection in Chrome DevTools, we observed multiple warnings such as
These violations appear only during tooltip hover events, causing noticeable UI lag.
Environment:
Framework: Angular 19.2.14
Browser: Chrome (140.0.7339.208)
Tooltip Version : (@progress/kendo-angular-tooltip": "18.5.2")
can you help with that? Thanks in advance.

import { CommonModule } from '@angular/common';
import { MenusModule } from '@progress/kendo-angular-menu';

In my project I have many tooltips for displaying different things. But I want to change the CSS properties of one tooltip in particular which will not affect the other tooltips. How to do it ,the method mentioned in the document doesn't seem to work.
<div kendoTooltip tooltipClass="my-class">
.my-class *{
color:black;
}
The calendar popup is not getting closed even after selecting the date or clicking outside.
This is how I have integrated data picker in my component.
</kendo-datepicker>


Hi,
I have a kendo-dropdownlist and I want to override the style of the kendo-popup. I want to change the font as well as change the style for the selected item (see attached file) like the background color, etc...
How do I go about doing this? I've tried styling using pseudo ::ng-deep, :host ::ng-deep to using the classes .k-popup, the li's .k-list-item, etc..
Thanks!
Jaime
