Are there compatibility issues with QTWebKIT and WebGL?

I created a Gem that opens a window in the Editor (an Editor Plugin like Substance as recommended by @petrocket). We use QT Webview to run our external web tool inside the Plugin. The web tool uses webGL and runs well inside the webview, but causes the Perspective View pane to stop rendering. Can you tell me if this is a known compatibility issue? Can we use QTWebKIT with WebGL?
