with export MOZ_WEBRENDER=0 Firefox works as expected so there seems to be a problem somehow

note that downgrading the virtual hardware version cause a startup crash with the STR - Bug 1371563

I can reproduce on MBP15 late-2013 model.

Firefox turns black immediately after launched into homepage with webrender enabled.

This issue only happens when hardware acceleration in VMWare fusion is enabled.

So maybe it is a compatibility issue with VM's GFX backend.

As with bug 1371563, unless this is blocking something important it's going to be a P5 for the time being.

Ok. It looks like the vm is just using llvmpipe. WebRender should work in that situation so I'm not sure what's going wrong here.
