337575 - Application switching (CMD+TAB or mouse-based) is broken, switching focus to Thunderbird main window horked

Status: RESOLVED DUPLICATE of bug 337334

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Patrick]

On a MAC using the CMD + TAB key allows you to switch between applications. Currently, when switchiing to Thunderbird, the main window does not get the focus.

Steps to reproduce
1. start Thunderbird
2. start Firefox
3. Press CMD+Tab

--> Thunderbird becomes the active application (visible by the appearence of its menu on the top of the screen), but the main window does not appear.

Pressing an additional CMD+` is needed to give focus to main window/make main window appear at all.

Maybe a patch for this bug could also address bug 318585?

Also happens with Minefield. Moving to Core.
Reproducibility is not 100%.

Attachment: Sceenshot of redraw issue

One more observation:  Related or not, but i'm also having redraw issues with 

Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20060510 Minefield/3.0a1

After application switching occassionally, much of Minefield is missing: (personal) toolbars, address bar, the actual page etc.

Patrick, can you find out what the regression range is?

I think this may've been caused by Darin's thread changes from that day. Seems like some of the follow-up checkins (bug 337824, bug bug 337550, bug 337481) also fixed this.

Marking as such --> fixed by checkin for (probably) bug 337824.

I'm still experiencing this, sometimes, with

Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20060521 Minefield/3.0a1

I wasn't, but I am now.

As I suspected, this occurs when you hit the new icon decoder code from bug 335723.  It's a slight variation on bug 337334.
