Help about SDL abnormal color display in VNC viewer.

[James Weatherall]

Paresh,

I'm afraid that you are mistaken.  What I described is the VNC Viewer's Low
Colour feature, used by default for slow connections.

The XRANDR extension affects the size of the X desktop, its rotation, and in
the latest spec the positions of physical display devices' viewports.  It
doesn't affect the X desktop's colours, so I'm not sure why you think XRANDR
is causing whatever "weird colours" you're seeing.

What is the "VNC session window resize problem" that you refer to?
