           Summary: TeamViewer: Screen grabbing is painfully slow
           Product: Wine
           Version: 1.1.34
          Platform: x86
               URL: http://www.teamviewer.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: caliga at arcor.de


In general, TeamViewer runs amazingly well with wine.
However, screen capturing done by TeamViewer is awfully slow.

The screen is grabbed if
- you do a presentation from wine to 2nd machine
- you do a remote support from 2nd machine to wine (currntly not working:
#12067)

The screen is grabbed like this:
BitBlt(MemDC, left, top, width, height,    ScreenDC, 0, 0, SRCCOPY);

On my machine, this takes about 1.1 seconds, but may very well depend on the
graphics board and driver in use.
