I experienced the same bug in winslop: It is not the neovim fault, but the terminal emulator. While WT (default for 11) is good enough, for some computers it is pretty laggy. I recommend wezterm.
Source: I manage many onprem windows PCs with automation, and some 1 of them experienced this issue.




I am happy that I’ve been useful 😄 The experience on windows will always be worse than on linux sadly. But I have no choice, I have to use winslop for work, so I made it work. 😅
