In both browsers we detect touch and display the touch specific control bar, but no touch events are fired. Edge does not support touch events by default. Enabling this can be done in the developer settings accessed by writing "about:flags" in the URL. IE does not support touch events at all. Some problems caused by this: Causes our "Active mouse button" to not work. In IE the cursor disappears after a touch because a mouseleave event is sent instead on touchend. The cursor also disappears on Edge when touch event support is disabled but it might be related to upstream bug: https://github.com/novnc/noVNC/issues/1300 Se also bug 5779
Both IE and Edge claim to support PointerEvent. Perhaps touch works better with that? Also see bug 7395.
As of bug 7550 we are dropping support for IE, which means that the IE part of this bug no longer is relevant. Edge has been rewritten and is now based on Chrome, so the issues there might have been solved. Testing of this still needs to be done before closing the bug.
Once IE support is removed from webaccess, we are free to remove all traces of nodejs along with all nodejs packages from cenbuild. Previously, nodejs et al. were used exclusively to provide polyfills for IE.
I could reproduce the issue in IE on Windows 10. But since we drop support for IE we will not fix this. However, the issue is gone in new Edge. Tested with: * tl-4.12.1 server on Ubuntu 20.04 * Edge Version 95.0.1020.53 on Windows 10
