1230716 - WebGL renders certain content upside down on Windows

Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

[Evan Wallace [:evanw]]

Attachment: trace.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.86 Safari/537.36

Steps to reproduce:

Open the attached file trace.html and view it in both Firefox (42.0) and Chrome (47.0.2526.73 m) on Windows. The attached file contains an extracted and reduced test case from our app (the WebGL design tool at figma.com). The machine is a HP Stream if that matters (http://store.hp.com/webapp/wcs/stores/servlet/ContentView?eSpotName=Stream11&storeId=10151).



Actual results:

Chrome renders right-side up while Firefox renders upside down. We've received a number of complaints from people using Firefox on Windows that the editor is unusable and were lucky enough to have a machine that reproduced the issue.



Expected results:

The Firefox rendering is wrong.

The graphics section of about:support says this:

Changing webgl.force-enabled and webgl-disable-angle to true makes the problem go away.

It looks like this was already fixed. Please test the current Firefox Developer Edition and reopen this report if you can still reproduce the issue.

Works for me, whether e10s is enabled or not.

Yes, it works for me in Firefox Developer Edition. Thanks.
