Yea, didn't think that was it.

One ugly workaround I found that seems to work:

    auto palette = canvas()->palette();
    palette.setBrush(QPalette::Base, QBrush(QColor(50,50,50)));
    canvas()->setPalette(palette);

Instead of

    setCanvasBackground(QBrush(QColor(50,50,50)));

Still don't understand why that won't work though.
