WebGL local html file loading fails



  • I am trying to use WebGL with the fancy-browser (webenginewidgets) example. When I open an html file with embedded webgl content from the web - it works, but when I open exactly the same html from local filesystem - the behaviour is unpredictable: sometimes it loads, sometimes - not, after refresh it usualy fails...
    http://daylight.ho.ua/ngl.htm - works in fancybrowser example
    file:///tmp/ngl.htm - fails
    In chromium/firefox both work perfectly
    Qt 5.5, ubuntu 14.04 x64
    Any suggestions, why this could happen would be appreciated.



  • Here are the screenshots depicting the problem:
    works from web
    fails from local drive
