Build ID: 20160822064441

Steps to reproduce:

1. Start Nightly
2. Go to "http://helloracer.com/webgl/"
3. Open DevTools > Canvas
4. Click Reload and Recording
5. Save snapshot in local
6. Import the snapshot
7. Check screenshot-image and screenshot-dimensions


Actual results:

- screenshot-image does not change when switching call item.
- screenshot-dimensions is always "0x0"


Expected results:

Is this intentional? If not, screenshot-image and screenshot-dimensions should be displayed correctly.

Can you check tomorrow's nightly (or a build off https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=7963ebdd52b93f96b812eff2eab8d94097147b9c assuming it goes green) to see if this is fixed by the fix for bug 1297370) ? I kind of hope so, but it's hard to be sure. :-)

Hello Gijs, Bug 1297370 was fixed, but this bug still appears...

Well, if you click on one of small screenshots at the bottom, huge screenshot at the right doesn't change, but if click on the slider at the top, the screenshot does change (yet becomes blurry).
It looks exactly like bug 984844, but I'm not sure. Better ask Victor Porof.
