I am seeing this as well, particulatly in 3rd-party installable apps like Inbox, Google Maps, Calendar. My guess is that any apps that are essentially web-containers will not work. Terminal works though, so that may be a good place to start.

Flashing with rc-proposed does not yield any improvements and devel_rc-proposed's flashing process appears to be broken, but it looks like there were changes this morning, so I will try again later after new updates are visible.
