#1459 VNC input character display corruption in xterm

[Benn Schreiber]

Configuration: Rpi3B+ with 2018-11-13 Raspbian Lite with xdm, tightvncserver, xterm and other X server stuff.

Output characters are fine, but characters typed as input to an xterm are corrupt on the screen. Looks like 2 characters are good, then the next 2 are successively worse, then it repeats.

Other points of note:

• No similar problem when connecting to an openSuse system
• 3 viewers (tightvnc, ultravnc, realvnc) demonstrate the same problem
• Not sure that it matters, but vnc started from xinetd (as it is on openSuse system as well)
• Same issue exhibited on an RPi3
• Also seeing it with uxterm and lxterm, but not in Firefox
• The issue doesn't occur if a TrueType font is used, but I prefer to use 9x15bold
• Scaling is set to 100%
• Have tried all encodings with same result

While it's not horrible, it's annoying enough that I'd like to get it fixed, and would appreciate any solutions or hints.
