I created a test Qt application (Qt 5.3) to simply load the facilities sample kml file using a QWebView, as soon as the data is loaded navigation/moving the globe slows down drastically. Removing the loaded kml and the globe is back to moving smoothly. Has anyone been able to load kml data without the non responsiveness?
I also created a test Qt application (Qt 5.4) using QWebEngineView and received the error that while my browser supports WebGL Cesium failed to initialize. Using the QWebEngineView, I went to https://get.webgl.org/ and got the following: “While your browser seems to support WebGL, it is disabled or unavailable.” I attempted to use 5.4 in an effort to see if the responsiveness would be affected or not but was not able to get to the point of loading a kml file.
Any help/info would be appreciated.
