Do a tcl state flush before accessing tcl vector space. This fixes some
more problems with flickering (bug #6637). drm may not be appropriate place for this, since doing that flush there might both be overkill and insufficient in some cases. However, it's hard to figure out when that flush is needed, so this has to suffice. There does not seem to be a performance penalty associated with it.
