--- Comment #12 from Harald Judt h.judt@gmx.at 2011-10-10 11:01:12 PDT --- I thought it was time for an update, but unfortunately this is still not fixed in 3.1-rc9. Isn't there anything that can be done about this? All in all, the driver works mostly fine, but the corruptions are very annoying and disturbing.
