Dynamically resizing flash content stops it being notified about focus gain/lost

[Alan Hazelden]

Binary package hint: firefox

Flash content normally receives an event when it gains focus and another event when it loses focus. The AS3 events are Event.ACTIVATE and Event.DEACTIVATE.

After resizing the content using Javascript, these events are no longer received by the flash application.

Note that focus is transferred normally: the flash application can still receive input as normal. It is only the _notification_ of focus gain/loss that is broken.

Steps to reproduce:

1. Visit http://www.draknek.org/misc/firefox-bug-1/index.html
2. Click on flash content (starts as a black rectangle) to give it focus.
3. Click outside to remove the focus.
4. Click the [x4] link to resize the flash content.
5. Click the flash content to give it focus.

---

Actual results:

Before resizing, flash content area turns green when focus is gained and red when focus is lost.
After resizing, flash content does not respond to focus changes.

---

Expected results:

Flash content area always turns green when focus is gained and red when focus is lost, before and after resizing.

Draknek,

I have tried to reproduce this using your steps on Ubuntu 10.10 Beta on Chrome 7 and Firefox 3.6.10. I am able to give focus to the flash block in both browsers before and after resizing. Is it possible to upgrade to a new version of Firefox and see if it is fixed? Also, do you know if this is specific to Ubuntu? Finally, one more question: What version of flash/flashplugin are you using?

Hi,

I have only been able to get one other individual to report this behaviour, he was also running Ubuntu 10.04 32 bit.

The bug does not occur in Chrome.

I am now using Firefox 3.6.9 and the bug is still there. The latest stable version appears to be 3.6.9.

I am using the flashplugin-installer package, Flash reports itself as version 10.1.82.76.

Cheers,

Alan
