I am not sure this is right. I believe I have used QPixmaps in non-main threads before. I think you just have to supply the device metrics (bpp, ARGB) rather than using the screen's metrics. QImage is device-independent. But if you choose your QPixmaps metrics to match you display, you should be optimized for drawing.

Sorry for not responding earlier...
See the QWebPage doc for using it without widgets (and thus in other threads).
You can only use QPixmaps in the main GUI thread. Try rendering to a QImage instead, which should work in any thread.
