@modulux @alexhall dang, that's weird. I'd poke with trying to change the paste shortcut in Windows Terminal, but I have little faith on that.
I'm really puzzled. There's many things about terminal emulation that can cause issues, like backspace not working, but it's been maybe a decade since I've suffered any significant issue. (Except for programs breaking under GNU Screen, of course.)
I'll go install NVDA, I've always wanted to play with it.
