I'm sorry I can't recreate this under Qt/X11 and I don't have access to
Qt/Embedded.  If you can run Mozilla under a debugger on Qt/Embedded and post a
stack trace of the crash, I would be in a better position to point you at the
problem code (or possibly even tell you how to fix it).  Without more
information like that, it is impossible to guess where the problem is...

No.  Other than the actual rendering and drawing itself, and possibly some timer
operations, X11 is not involved in rendering, even with Qt/X11.
