Steps to reproduce:

Relaunch Firefox after a fresh reboot on Windows 8.1

Actual results:

The back button turns into a diamond (no themes installed) on the second launch.

Expected results:

A round button every time you close and reopen firefox.

Do you have any add-ons installed? Do you still see this bug if you disable them?
None installed. Also still occurs after resetting Firefox and completely reinstalling.
After toying around with things, the bug seems to be caused by having tessellation disabled in my PC's 3D graphics settings. Re-enabling it returns the button back to its normal shape. The only reason why I wasn't getting the diamond shape on the first launch after a boot was because Firefox launches faster than AMD's Catalyst Control Center.
