The machine that is the client is a 64-bit Windows 10 machine with dual 1920×1080 monitors connecting to a 64-bit Ubuntu 18.04 machine running dual 1920×1200 monitors.
The problem is that on connection only one of the two server-side screens is matching the client’s resolution. Specifically, the left monitor (which is not the “primary display”) resizes properly, but the right monitor (the primary display) does not. The resolution settings on the Linux box are both set to 1920×1200 (NOT “Auto”).
The problem might be TPBCAK (The person between computer and keyboard) but maybe someone has some insight or has had this problem themselves?
