Recently I found that window borders keep disappearing intermittently in Unity! Especially when either Google Chrome or Mozilla Thunderbird are running.
Is there a way out?

Usually restarting unity helps. You can do this by Alt+F2 and then typing:
unity --replace
Note: Don't execute this command in a terminal otherwise unity will be killed, when the terminal is closed.
This is of course not a fix. Just a way to undo the error once it has occurred. I suppose these bugs (and the ones posted in my comments to your question) will be fixed with future updates. There are many bug-reports on launchpad concerning these.
You could also try ans install CompizConfig Settings Manager / sudo apt-get install compizconfig-settings-manager
and play with the setting there. It might or might not help - depending on who you ask.
Have you enabled keeping minimized windows thumbnails under "workarounds" in ccsm? If so, disable it -- it messed up my unity bad.
I fixed this issue permanently by entering CompizConfig Settings Manager (CCSM) —if you don't have it do sudo apt-get install compizconfig-settings-manager
—, going into the Window Decorations options, and changing the Command setting to compiz-decorator
.
Backing out of this menu, then unchecking Window Decoration, allowing the desktop to reload, then checking Window Decoration and exiting out of CCSM.
After doing this, I can no longer reproduce the issue.
