WoW login screen, with artifacts

The input fields and menu items on Warcraft's login screen are now being misrendered; things are appearing and disappearing, apparently at random.

Git bisect points the finger here:

    pb: add void * for flush ctx to mapping functions
    
    If the buffer we are attempting to map is referenced by the unsubmitted
    command stream for this context, we need to flush the command stream,
    however to do that we need to be able to access the context at the lowest
    level map function, currently we set the buffer in the toplevel map, but this
    racy between context. (we probably have a lot more issues than that.)
    
    I'll look into a proper solution as suggested by jrfonseca when I get some time.

It's not only WoW, there is some flickering in Heroes of Newerth and also some missing stuff in Unigine (window glass in Unigine Sanctuary). I haven't bisected HoN so far but with Unigine Sanctuary git bisect shows above mentioned commit. This is with r300g driver too, RV530.
