Bug Description
I suppose this is a bug with the nvidia driver, but I'm not sure. After the second-to-last routine software update (which I think updated the nvidia driver), changing window content is only refreshed if the window is moved.
Ubuntu 12.04.5 LTS, kernel 3.2.0-91-generic,
NVidia driver installed: 340.93-
Thinkpad laptop with nvidia graphics card (see below),
Window manager: Gnome Classic
How to reproduce the bug: Log in under Gnome Classic. Open Gnome terminal. Execute some command (ls). Open new tab in terminal. Execute some other command (ps), just to have different tab contents. Switch back and forth between the tabs using the mouse. After some switches, neither the tab rider is activated nor the tab content is refreshed any longer. Only if you move the window, the tab rider gets activated and the tab content is refreshed. The same problem occurs in other applications (e.g. in thunderbird when selecting an email --- email list entry is not marked and email content is not shown, only if you move the window), so it is not application-
The bug disappears when using the window manager "Gnome Classic (no effects)" instead (which is "non-compositing" in contrast to "Gnome Classic"). The bug is also present in other window magagers ("Ubuntu").
Side remark: I tried but failed to switch back to an earlier version of the nvidia driver (from 340 to 331) using synaptic: When deinstalling 340 and installing 331 instead, synaptic complains that it depends on 340. So I can only guess that the bug is caused by the nvidia driver.
Any help would be highly appreciated as the bug is really annoying.

Just an addition: The bug shows similarities to this one, although it was only reported for Firefox:
https:/ /bugzilla. mozilla. org/show_ bug.cgi? id=1194358
Users report that compiz may cause the problems, and that would explain why the problem isn't present when using "Gnome Classic (no effects)" as compiz is not running there (but metacity).
So maybe the problem is compiz, not the nvidia driver?
