Status: RESOLVED DUPLICATE of bug 952267

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

Description

[gbennett]

Attachment: KeyboardLagLOG.txt

Description:
When the user is adding a new contact or editing an existing contact, they will notice that when they are typing at a fast rate on the keyboard, the letters are lagging way behind the user's input. Sometimes, the letters don't even show at all even though they were typed by the user.

Repro Steps:
1)  Updated Buri to Build ID: 20140102040201
2)  Tap on the "Contacts" icon.
3)  Tap on the "+" icon to add a new contact. 
4)  Tap on the "Name" field and immediately start typing a bunch of different letters at a fast rate.
5)  Tap on the "Last name" field and type a lot of letters at a fast rate.

Actual:
Severe lag occurs when typing at a fast rate on the keyboard when entering text into the edit contact form. Sometimes, the letters typed do not appear at all.

Expected:
When the user taps on a letter on the keyboard, it immediately appears in the text field without delay.

This is very likely a regression from bug 942790.
