I have been facing this issue for a while now.
Some details of my system are as follows:
System: Host: sitspak Kernel: 4.4.0-22-generic x86_64 (64 bit) Desktop:

GLX Renderer: Quadro K2100M/PCIe/SSE2 GLX Version: 4.5.0 NVIDIA

I have observed following:
1. This happens when a external usb webcam is attached; dmesg regarding
camera is as follows.
uvcvideo: Found UVC 1.00 device A4 TECH HD PC Camera (0ac8:3500)
[ +0.000882] input: A4 TECH HD PC Camera as
/devices/pci0000:00/0000:00:14.0/usb3/3-10/3-10:1.0/inpu
[ +0.000116] usbcore: registered new interface driver uvcvideo
[ +0.000002] USB Video Class driver (1.1.1)
2. My themes fall back to classic gnome as well. To get around I restart
lightdm service.
3. It was worse in Ubuntu 15.10 but in 16.04 some window decorations, icons &
fonts fall back.
4. A dmesg related to Nvidia which might be interesting:
ACPI Warning: \_SB_.PCI0.PEGP.DGFX._DSM: Argument #4 type mismatch -
Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95)
Hope this helps!

Ubuntu 16.04 crashes immediately on login. Default settings not
applied and appearance is a bit ugly (incorrect font hinting, in-
window menus etc).
