As a data point, if it is relevant, rxvt has always worked from El Capitan, which was when I bought this Mac, to Catalina today. Not sure if that is important, but, it is an observation. ETerm was not working, but, I haven’t upgraded it since the MacPorts upgrade. I normally used Apple’s Terminal, and iTerm, but, xterm, et al, are useful once in awhile, which why I keep them around.
Another point, the last time I installed xterm prior to today, the operating system was Catalina 10.15.2. When I upgraded MacPorts today, my machine had been upgraded to 10.15.3 in the interim. Your point about potential point upgrade to the devices fixing the bug could be on point.
