ArcGIS API for JavaScript 3.x applications freeze when accessed through Microsoft Edge browsers

Last Published: May 8, 2024

Description

ArcGIS API for JavaScript 3.x applications freeze when accessed through Microsoft Edge version 124.0.2478.51 or newer.

The behavior is seen when clicking on pop-up or widget elements, such as a checkbox or close button, cause Microsoft Edge to freeze and become unresponsive for an extended period of time. 

This issue affects Microsoft Edge 124-126 versions on both Windows 10 and Windows 11. 

This issue has not been observed in Chrome or Firefox.

Products affected:

  • ArcGIS API for JavaScript 3.x
  • ArcGIS Web AppBuilder
  • ArcGIS Configurable Apps
  • Map Viewer Classic

Cause

This issue is caused by an SVG element hit test performance issue associated with a recent Microsoft Edge update.  Hovering over or clicking on an element that has CSS "cursor: pointer" style causes the Edge Browser UI to freeze.  The duration of the UI Freeze is proportional to the number of SVG elements involved.

There is an existing Chromium issue for this behavior that we are monitoring: Significant Degredation in SVG 'Hit Test'/ click event speed.
