      We are using WebGL to stream a QtQuick application to view it in a browser. As soon as animations are running the UI is flickering massively for some time (~25s while testing). We have been using the Qt OPC UA demo showcase from basysKom. You can see the flickering in the attached video.

       

      This has been tested on Qt 5.11 and 5.12 RC2 on Linux in Firefox and Chrome.
