Michael Jumper commented on GUACAMOLE-439: ------------------------------------------ This is not a bug within Guacamole, but rather an unfortunate fact of IE's slow implementation. If IE is incapable of processing the data received by Guacamole without blocking handling of mouse events / interactivity within the browser window, I don't think there's anything we can do to help it along. Guacamole's processing is already extremely streamlined, with much of the decoding process offloaded to browser-native image decoding which runs in the background. I'm not sure whether IE11's dev tools has a working/useful profiler. If it does, and you can run Guacamole within the profiler, that may reveal what is slow in IE but not in other browsers. Beyond that, I doubt there is an actual Guacamole-side performance problem to be resolved here. > Mouse movement in IE 11 is very irritable. It's not smooth as it is with > other browsers. > ---------------------------------------------------------------------------------------- > > Key: GUACAMOLE-439 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-439 > Project: Guacamole > Issue Type: Improvement > Components: guacamole-common-js > Affects Versions: 0.9.13-incubating > Environment: Internet Explorer 11 > Reporter: Amarjeet Singh > > Mouse movement in IE is very irritating. It stops, hangs and there is > lagging as well. It affects the whole user experience while scrolling as > well. If there is a file of more than 5000 line and I want to scroll, it > hangs in between and starts again. Mouse movement breaks in between. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
