Description

[guigs [:guigs] PST (please needinfo me!)]

+++ This bug was initially created as a clone of Bug #951443 +++

When using the BasicCompositor, CG prints many warnings complaining about null contexts. These contexts come from the UnboundnessFixer which tries to create a CGLayer with 0x0 size.

Reference to support thread: https://support.mozilla.org/en-US/questions/1026643 

"clean-installed OS X Yosemite, running Firefox 33 and getting TONS of "CGContext..." errors, such as these:

   CGContextTranslateCTM: invalid context 0x0
   CGContextScaleCTM: invalid context 0x0
   CGContextSetAlpha: invalid context 0x0
   CGContextSetShouldAntialias: invalid context 0x0
   CGContextConcatCTM: invalid context 0x0
   CGContextScaleCTM: invalid context 0x0
   CGContextSetInterpolationQuality: invalid context 0x0
   CGContextDrawImage: invalid context 0x0
