I'm not sure why, but Unity crashes fairly often (roughly every 15-20 minutes).
I get various bugs, for example when I try to click on the top panel, it simply becomes transparent. The same thing often happens with the launcher on right.
As a somewhat separate (however related) note, very often, the window decorator crashes and doesn't restart automatically.
As a workaround I have a shortcut on my desktop to
unity --replace, although this restart doesn't often last very long. Running
unity --reset also doesn't seem to help me much.
It gets especially unbearable (crashes far too often) when running certain heavier applications such as Google Chrome and Netbeans, full screen.
Does anyone have any suggested fixes? Or perhaps this has been discussed elsewhere, such as on Launchpad?
