Bugzilla Bug 38481

In WindowMaker, it seems that GTK2 applications can cause a focus/flicker
problem when switching workspaces.  For example, when the user switches to a
workspace containing overlapping GTK2 windows, the titlebars flicker and focus
seems to infinitely jump between the GTK2 windows.  This bug manifests itself
when sloppy focus is enabled. (Input focus mode: Auto)

I believe this is a known issue, but has not yet been resolved by the
WindowMaker folks.  Debian includes a patch in their package to resolve this
issue, as noted in the changelog, which can be found at the following address:

http://packages.debian.org/changelogs/pool/main/w/wmaker/wmaker_0.80.1-8/changelog

Reproducible: Sometimes
Steps to Reproduce:
1.Open multiple overlapping GTK2 windows (eg., MozillaFirebird), positioning
the mouse above the topmost window
2.Switch to another workspace, without moving the mouse
3.Switch back to the workspace containing the GTK2 windows

Actual Results:  
In roughly 3/4 of the trials, the window focus jumped between the two
overlapping GTK2 windows, causing the title bar to exhibit a flickering effect.
 In some of the trials, this ceased after a couple of seconds, and gave focus
to
the bottom window.

Expected Results:  
Given the topmost GTK2 window focus.

I see this with Bittorrent and gaim all the time.  Its really annoying and
leaves me wondering what is using 100% of my cpu all the time.  I don't use
sloppy foucus though.  And I only see it when new windows are opening, not when
switching desktops.  I'll test the patch and update this bug.

I will also test the patches.  I have seen this before but I never thought much
about it.  I'll get this fix in asap if it does what it's supposed to.

Well I've been using the patch for 3 days and I haven't seen the flickering.  I
did probably 20 - 30 actions that used to cause it frequently, and no
flickering.

er... make that 2 days...silly timezones

I Used the debian patch in the past and I can testify that the flickering is
gone.
I used it for 6 months or so....

-r4 is now in portage and includes this fix.  Thanks for being so patient while
this made it's way into portage.  If you find any problems, feel free to
re-open this bug.
