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.
