I use VNC to connect to a remote machine, but quite frequently the client crashes with the error "Rect too big". it's really annoying :/ why does it happen? is there a fix/workaround? I'm using TigerVNC.
There is an issue with ZRLE implementation.
Use Hextile. Although RealVNC should have this bug fixed now, you may want to use it instead of TightVNC.
