Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Video, defect)

Attachment: Logs of disappearing video listing menu bar

Description:
If the user taps the screen rapidly while there is a video playing, the menu bar on the main listing page may not be visible when the user returns via the Back icon.

Repro Steps:
1) Update a Tarako to BuildID: 20140422014001
2) Launch the Video app and select a video.
3) Rapidly tap the screen for a few seconds so that the title and menu bars blink in and out rapidly.
4) Tap the back button and observe the video bar at the bottom of the page.

Actual:
The user is returned to the video listing screen and the menu bar at the bottom is either blank or shows graphical corruption.

Expected:
The user is returned to the video listing screen and the menu bar at the bottom appears normal.

I've occasionally seen this without the tapping and have seen a black screen instead of a preview just by hitting the back button.  I repro'ed this at a lower rate.
