Adding this to my app.scss solved the problem in my case

.x-paint-monitor.cssanimation {
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;
    -webkit-animation-duration: 0.0010ms;
    animation-duration: 0.0010ms;
}

The duration of 0.0010ms was the minimum that worked well.
