[VncViewer] Rect too big trying to connect ro my local TiverVNC server

[stefanofornari]

I have setup a TigerVNC server and configured it to stream one application window. When I run VncViewer, I get the error below

CConn: connected to host localhost port 5905
CConnection: Server supports RFB protocol version 3.8
CConnection: Using RFB protocol version 3.8
CConn: Using pixel format depth 24 (32bpp) little-endian rgb888
CConn: Requesting Tight encoding
CMsgReader: Rect too big: 17152x7168 at 2304,4098 exceeds 1280x720

It looks like a bug in reading the protocol, but I really do nothing about the RDP protocol. I am available to provide any help to fix the issue.

This happens with Autoselect or Tight encoding; if you open the options panel and selected another encoding the streaming starts. However (maybe this should be another bug), most combinations of options do not work cleanly: portions of the screen show scrambled/noisy.
The only combinations I found working are:

• zrle/No JPEG/Compression=0/No Local Cursor
• raw/No JPEG/Compression=0/No Local Cursor

Hope this helps.
