652948 - First character typed in form is invisible

Status: VERIFIED DUPLICATE of bug 655852

(Firefox for Android Graveyard :: General, defect)

Description

[Matt Brubeck (:mbrubeck)]

Attachment: screenshot after typing "A"

Steps to reproduce:
1. Open http://people.mozilla.com/~mbrubeck/test/form.html
2. Tap in the text input box.
3. Type a letter.

Expected results: The letter appears in the input box.

Actual results: Depending on which letter you type (and possibly on the contentns of your form history?), the caret moves but the letter is not drawn, or is not completely drawn.  For example, see the attached screenshot where only about one pixel of the letter "A" is visible.  After typing another letter, or tapping elsewhere on the page, the letter becomes visible.

I can reproduce this on trunk Galaxy Tab and T-Mobile G2 with both Swype and Samsung Keypad.  I can *not* reproduce it with the "Android keyboard" input method.  (I think this is because "Android keyboard" has suggestions enabled, so it sends the letter as a composition.)

I can't reproduce this on Aurora, so this is a regression since Firefox 5.0 merged to mozilla-aurora.

I thought I saw this on desktop Linux Fennec too, but can't currently reproduce it there.  I might have been mistaken.

Could this be a regression from bug 649666, or bug 649583?  Or maybe bug 637671?

[Brad Lassey [:blassey] (use needinfo?)]

sounds like its time for a bisect

I'll see what I find tomorrow.

The first bad revision is:

summary:     Bug 649583 Panning regression on google reader in 2011-04-12 nightly r=roc

What is screwy is that bug 649583 is checked into Aurora and I don't see this problem on Aurora.

I'll look into it.

I'm seeing this regression or perhaps a very similar issue on my 05/16 Nightly. In comment #0, there is mention of very minor drawing, but I am not seeing any drawing of my first character until the content is repainted (device rotation)

Device: HTC Nexus One
Keyboard: Android Stock

Spoke too soon, if I squint I can see a very slight paint on the character 'r'. It appears I'm running into this very bug.
