348931 - xul edit box doesn't tell caret to stop blinking

Status: NEW

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

I've only reproduced this with a cocoa-cairo build, because that's the only place where I had printfs in place to tell me when certain painting was happening.

Steps to reproduce:

1) Open Preferences
2) click in home page edit box
- observe invalidation/painting start to happen every second as the caret blinks (need some printfs etc. in the relevant code)
3) click on another pref pane (e.g. "Content")
- observe invalidation continuing; I assume that it's just repainting the area where the caret used to be
4) click back to Main
- observe edit field not having focus, and invalidation output stops
