Metacity titlebar odity

[Trey Earl]

When clicking on metacity titlebar, metacity will crash and restart... if you do
this enough times, it will also fail to restart after the crash, user is left
with no application window.

Happens with 2.9.5-1 ... very irritating :(

[Sebastien Bacher (seb128)]

no crash here. Where do you click exactly, what focus mode are you using, do you
know how to get a backrace ?

[Trey Earl (lunitik)]

Not sure how to backtrace no...

I am using "roll-up" if that is what you mean by "focus mode"?

Also, simular happens when closing applications... pretty much any interaction
with metacity itself it seems...

If you'd like to provide info on how to backtrace, I'll see what I can come up with?

Using "sloppy" focus, metacity segfaults pretty consistently - either creating
new windows, or changing workspace:

every time I try to move windows metacity keeps redrawing them without moving
them actually. Resizing works but it redraws windows (blinking) too. If I try to
move or resize a windows, all opened widows disappear and then come up.

[scoon (scoon2004)]

This happens to me as well. I can switch from window to window by clicking on
anything but the title bar. As soon as I try and move the window or click on
the title bar, all of my open windows get redrawn. If I have windows on other
desktops then they get redrawn as well. Once all of the windows are redrawn,
the original window that I moved is in focus again.

[Sylvain BERTRAND (sylvain-bertrand)]

Got exactly the same issue... Everything back to normal with:
 - libmetacity0 1:2.9.5
 - metacity 1:2.9.2
May help to narrow down the pb.

[Étienne BERSAC (bersace)]

on ppc with metacity 2.9.5-0ubuntu1, libmetacity 2.9.5-0ubuntu1.
When a window is moved or on window deletion:
 * all window from all desktop are show without borders.
 * all non-maximize window are drawing just "one height of title" below.
 * the workspace applet does not show anything.

Hi everyone,

This crash is my fault; the attached patch should fix the issue. Could others
try it and verify for me, so that I can roll a new upstream release? (This is
the same patch as in the upstream
http://bugzilla.gnome.org/show_bug.cgi?id=165093)

Thanks,
Elijah

[Sebastien Bacher (seb128)]

thanks Elijah for the patch. That fixes the issue apparently.

[Sebastien Bacher (seb128)]

 metacity (1:2.9.8-0ubuntu1) hoary; urgency=low
 .
   * New upstream release:
     - fixed the 2.9.5's crasher (Hoary: #5823).
