[Bug 779387] Re: displaying and mouse calibration problems

[Christian Andrade]

I have the same bug.  It tends to happen when I have opened a web
browser in the same workspace (usually Chromium) and then bring
thunderbird back to the top.

When the bug occurs a black bar is produced below the top menu bar, so
thunderbird looks like it has been "pushed" down visually, but the mouse
point is still reacting as if the blank bar is absent.

I have tried re-minimizing thunderbird to see if that would reverse the
problem, but that method is ineffective.  The only way to reverse the
problem is to close thunderbird and reopen.  This has become a daily
issue for  me.

Ubuntu 11.04 64 bit, Thunderbird 3.1.10, IMAP with two accounts.
