I have set 'desktop-scaling' to off in my xpra.conf file, but nevertheless, whenever I connect my client (running on Windows 7), my application windows are scaled to 125% or 150%. Is this a bug, or have I misunderstood what the 'desktop-scaling' setting does in xpra.conf? I have tried this both with 0.17.5 and the 1.0 beta.
