1263749 - OSX Browser window stops stretching, goes black on right/bottom edges

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect, P3)

Description

[Catchlight]

Attachment: Firefox Screen Resize Issue.mov

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160407164938

Steps to reproduce:

On OSX 10.10.5 with a 4k large screen, I stretch the browser window out to a large size. (Approx Beyond 4300px wide at 142dpi)


Actual results:

Firefox stops stretching and black appears at the right side and bottom of the screen. It appears that toolbar items are not represented properly too, because once the black areas start, then the toolbar items are not re-drawing until you click on them.


Expected results:

Firefox should continue to expand beyond 4300px wide.
