Description Pierre Ossman cendio 2023-10-05 15:35:25 CEST 
ThinLinc (Xvnc) currently refuses to resize a session to anything larger than 16384 pixels in either dimension. This limit was added to avoid overflowing signed 32-bit calculations:

Most users should stay way below this limit, as it would mean more than 4 UHD monitors side-by-side. Some extreme video walls might exceed this, though.
