1314067 - Flash animation contains artifacts

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

Attachment: Bugzilla_Firefox+Flash.png

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20161019084923

Steps to reproduce:

I went to a website which I use to store and score flash-based presentations for my students.


Actual results:

In the opening screen, a short animation sign-in box appears, with artifacts. After the sign-in, the sign-in box animation folds back up - which also has artifacts. There is a short video clip which shows the problem here:

I am running Windows 7 Pro 32-bit with Firefox 49.0.2. The problem does not occur and the animations show correctly under up-to-date versions of Edge, IE, and Opera.


Expected results:

The sign-in box and loading animations should not have artifacts.
See the video link above, and the attached image.

Close bug, please.

For some reason, I now cannot reproduce the artifacting.
