995849 - Performance issue / screen artifacts entering text in <input>

Status: RESOLVED DUPLICATE of bug 993554

(Firefox for Android Graveyard :: Toolbar, defect)

Description

[Mark Capella [:capella]]

I wasn't sure which component to file this in. (I don't think it's a Keyboard/IME issue ... but maybe).

I notice significant pauses and screen artifacts after entering enough text into an <input> field (causing the text to scroll left as the cursor maxs out on the right side of the element).

Here I demo by repeatedly tapping InputMethod (Swift) suggestions on an N7, but I can also repro using stock Google keyboard and just typing key streams like hjgjhgkhjgkhjgkhjgkhjgkhjgkgkhg and so on.

Sounds like something that would cause significant frustration.

I think it's a gfx issue.

Attachment: Low-res <input>

On my Galaxy Nexus, if I keep entering text, eventually any new text will be in low-res mode. After that, panning the input field results in glitches a lot of times.

I'm assuming this is a regression, based on the dependency on bug 996062? If so, let's tag it as such.  Right now, tracking this one as a blocker to bug 996062.

Same issue as bug 993554.
