Doesn't happen to me, but I am on Linux with basic layers. Seems to be an issue on Mac.

Confirm on Windows x64 build OS ver: x64 8.1 Fx ver: 31.0a1 trunk 140411

This might actually be bug 995745.

blassey says that milan says that mattwoodrow is investigating this regression.

Let's see if we get traction in bug 995745 and figure out if it is the same as this one. I did ask Matt to take a look, but I'm not sure he actually signed up for it quite yet :)

I suspect this may be related to a bunch of e10s WebGL reftest failures that happen on Mac and Windows. Here's an example: https://tbpl.mozilla.org/php/getParsedLog.php?id=38282229&tree=Holly&full=1#error12

Here's an example: > > https://tbpl.mozilla.org/php/getParsedLog. > php?id=38282229&tree=Holly&full=1#error12 So what those failures say is that WebGL isn't getting anything to the screen at all. No WebGL app display at all while those reftests are failing.

This is probably going to be fixed by bug 997758.

(In reply to Matt Woodrow (:mattwoodrow) from comment #7) > This is probably going to be fixed by bug 997758. We should probably just fix this separately. I don't think there's any reason for this to be blocked by 997758

OK. I had added the dependency on bug 997758 mostly as a reminder to test whether it did fix this bug.

WFM on Windows. Fixed by bug 995745 perhaps?
