Attachment: screenshot2.png

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151229124331

Steps to reproduce:

Using Qubes 3.1 Release.
This is Xen which runs a Fedora-23 virtual machine.
Run Firefox-42 or Firefox-43.0.3 in Fedora-23.
Attempt to use full screen using F11.


Actual results:

Most elements stop being redrawn, like the web page, visible tabs, new tab button, etc.
Some elements (Webpage content) are redrawn after some events like window resize or clicking F11.


Expected results:

Webpage changes on scrolling, new tabs are visible in tab menu, etc.
