Description Matthew Francis 2015-03-18 04:48:25 UTC
Reproduced on OSX 10.10, LibreOffice and later ( and earlier are not affected)

The images contained in attachment 113502 [details] of bug 89473 render as all black at zoom levels greater than around 65%. This does not appear to occur on Linux.

These two bugs both relate to all-black images, so they are probably related in some way (some characteristic of the images?), but they begin at completely different points in history.

Confirmed on master 

Build ID: 93b0b5b71dc1251ea2f1873b42b2e5f82bf9d9e4
Locale: fr_

OSX 10.10.2

where the images are black at document magnification above 90%
Comment 2 Matthew Francis 2015-04-10 16:56:51 UTC
OSX bibisect points to a very small range in which the below looks like the only possible candidate. Exactly why this would only affect OSX is unclear.

Checked f5d69b2b8b002ca6905496a9d9065ef76b5641d7, that just unifies handling. The same graphic gets painted in the backend. I see nothing mac specific. Unfortunately I have no access to a mac, but probably is something in the graphics backend that gets slightly triggered different. That it's not in the common part is pretty safe to say since it works elsewhere

I have no mac, so have to restrain
