For me that happens in other cases such as web browsing or opening a terminal

In my case the crash occurred when opening an odp-presentation.

mine happens when press Alt+TAB frequently

Banshee was scanning the music directory. In the Alpha before this one, banshee finaly worked, now again problems

This happened to me while re-authorising an account under Gwibber.

This happens randomly, when I'm doing many different things.

Compiz is also crashing for me in many different situations causing the window borders of unmaximized windows to disappear. Have not yet found a way to reliably reproduce this though it happens nearly every time I run natty.

Sufficiently similar to my case that I suspect it's the same problem. I have Banshee open and was changing the volume using the "panel" applet when Compiz crashed. Lost all my window title bars but everything else carried on OK, including the Unity Launcher.

this is still happening. why is it "fix committed"?

for me, too. Happened today after closing a wine-app.

still happing for me too. Everything is updated today though.

does "fix committed" mean there's a fix in upstream, but not yet released as a package in the repos, or it means we shouldn't see the error?

Means that the person assigned to fix the bug is commited to fix
the time to fix is set on the milestone

Crash again on different actions e.g. change window size

Crashed while opening the appearance preferences window. The window title bars disappeared.

I just entered my information in bug 750550 and marked as duplicate of this one. In my case the screen starts flickering, but eventually the X server starts again and everything seems to come back to normal.

zzeroo: Please test with the last version of u-w-d, the fix has been released now in natty.

* on some Java application (IntelliJ) when a error dialog dispose.

Hi for me also now systematically crashes when I close a Java application (Hattrick Organizer)
in dmesg I read:

Still happens in natty after closing java applications (not always)

Same here after java dialogs:

Still happens for me too, especially for java dialogs.

I use a bibtex tool called jabref and can reproduce the crash simply by opening the dialogs of jabref.

Still happens for me, again with java dialogs.

Same here, also Java dialogs. (Intellij IDEA 10.0.3, in my case.)

Maybe it's a regression of some sort? Because when I used emerald in older
versions of ubuntu, it also used to crash quiet often after closing java
windows.

Best,

This is happening for me quite often - can't determine the actual steps to replicate. The interesting thing is that on the workstation that this bug occurs I have the ATI catalyst driver installed. On my laptop with the nvidia driver is has never happened.

The above happens with both the Ubuntu and Ubunt Classic themes. In the Ubuntu (unity) them I also loose the top panel (pixel corruption).

I have added an up-to-date crash report on https://bugs.launchpad.net/bugs/789513.

There are cases where compiz crashes, too. See https://bugs.launchpad.net/bugs/789498.

It seems to have resurfaced in 14.10. Mine crashes on boot, then restores itself.

It's highly unlikely you're seeing a three-year-old bug resurface in a component that has not been shipped for at least two years.

It's more likely you're seeing bug #1366351.
