[Joshua Mitchell (Inactive)]

[Blocking Requested - why for this release]: Regression, highly visible, poor UX

Comment 5

[Cristian Rodriguez (:crdlc)]

Kevin, do you think what this is something related to Gecko?

Comment 6

[Candice Serran (:cserran)]

Need confirmation if this is happening in other places

Comment 7

[Candice Serran (:cserran)]

Milan, can you take a look at what's going on here. Team thinks it might be GFX related

> Kevin, do you think what this is something related to Gecko?

This could possibly be a graphics issue. This bug has regressionwindow-wanted on it, so I'm hoping that we can get a useful regression range here.

[Milan Sreckovic [:milan] (needinfo for best results)]

I know we don't officialy test on JB builds anymore, but it would help us to know if this reproduces on the same versions, but JB.  Also, video would help.

Possibly caused by Bug 1048009?

Comment 14

[Milan Sreckovic [:milan] (needinfo for best results)]

If this is limited to this scenario, we may be OK not blocking for 2.1 (but should block for 2.2), but if it's representative of a more common problem, then I'd block.

Comment 15

[Marcia Knous [:marcia]]

In my testing scenarios, I have customarily only seen this once, and in homescreen. ni on the remote testing team to see if they have seen it outside the homescreen and more than once in a testing session.

Comment 16

[Gregor Wagner [:gwagner]]

Not blocking based on comment 15

Comment 17

[KTucker [:KTucker][Inactive 3/4/2016]]

In reply to Comment 15, the test team only ran into this issue once or twice at most during their testing when not trying to follow the steps in Comment 0. It has only occurred on the homescreen.
