--- Comment #3 from Stefan Dösinger stefandoesinger@gmx.at 2010-04-09 08:56:25 --- Apparently there's no complaint about dropping asynchronous buffer updates in this log. However, such a line would be printed only once for each affected buffer, so if you attached just the end of the terminal output it most likely won't be there. Please either grep the log yourself, or compress and attach a full log, not just the last part of it.
