Bug Description

[Impact]
No impact to regular users except possibly in how gracefully the system recovers from compiz crashes. Mainly impacts usability for developers who are starting and stopping compiz regularly. When compiz is closed down (typically as a result of replacing the window manager) it incorrectly dumps windows into the first workspace.

[Development Fix]
Revision 3092 of lp:compiz-core (in both 0.9.7 and 0.9.8 series). Defer call to window->windowNotify (CompWindowNotifyUnreparent) on shutdown.

[Stable Fix]
As above.

[Test Case]
1. Compile and run compiz-core from source.
2. Place windows on different workspaces (usually requiring compiz-plugins-main too).
3. Kill compiz gracefully (SIGTERM).
4. Restart compiz
5. Verify all your windows have not moved to workspace 0.

[Regression Potential]
Low. This fix has been well tested for almost 2 weeks so far. Initially it did trigger a regression, bug 981703. However we found that this fix was not the root cause of that bug, only a trigger. That regression is also fixed in this same release - 0.9.7.8 & 0.9.8.0. So there are now no known regressions.

ORIGINAL DESCRIPTION:
When compiz is closed down (typically as a result of replacing the window manager) it incorrectly dumps windows into the first workspace.

Doesn't seem like it (at least the fix for this isn't a fix for that).

Fix reverted in lp:compiz-core at revision 3093. It was causing regression bug 981703.

Hello Alan, or anyone else affected,

Accepted compiz into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

It's not fully functional. I've put maximized firefox in 0,0 - a terminal in 0,1 - nautilus in 1,0 - and system settings in 1,1. All stayed there except the terminal (which moved to 0,0 on compiz --replace). The terminal moves back to 0,0 no matter what workspace I put it on.

Further, if I use compiz --replace while on a non-0,0 screen, it will move the windows randomly to different workspaces.

needless to say, it's half-baked.

I've found the same. Most of the windows-moving-workspaces-when-compiz-restarts bugs are still present for me.

But this particular bug is not important enough to care about if it fails SRU verification.
