When users connect to the physical desktop of a remote machine and VP8 encoding is enabled, they get a white screen.

This occurs only when connected from Windows.

As a workaround, use the H.264 encoding (default):

- Click on the !M icon in the system tray -> Show the service status' -> Server preferences -> Performance
- Choose 'Use a specific display encoding' and select 'H264'.

To set it manually instead, edit the /usr/NX/etc/node.cfg file and set:

EnableDisplayServerVideoCodec 1

DisplayServerVideoCodec h264

Note: white screen occurs also when MJPEG encoding is set.
