Ok, I have written in a an horrible english, I hope this will help:

Open the chat and try to press two letter (or more) together like 'A' an 'S'
some times on the edit box of the chat windows and the chat will loop. Sometime
you can stop looping changing focus to another windows.
(While looping due to keyboard with WINEDEBUG=+msg we can see two repeated
messages "TeamViewer DeferredUpdateRect" and WM_KEYDOWN)

This behavoiour can be seen (with more difficulties to replicate) also with
mousewheel or quickly presssing mouse buttons and it's not keyboard-only
related.

The problem happens only in wine.
I think the component is user32 'cause with the patch Teamviewer works fine.
