have you filed a bug report? Dual-head settings appear to have bugs and
quirks that are either associated with the window manager or X. I learned
how to avoid the bugs, but the best thing to do is to report them. Testing
under these 'conditions' is probably not a top priority.

I have a similar issue wherein screen 2 dies completely and I have to restart

I use KDE by the way. I never tried dual-head settings with GNOME. One more
reason to favour KDM/E? ...
