I suspect that the terminal emulator does things that Emacs doesn't
expect.  There's an entry in etc/PROBLEMS about problematic behavior
of another emulator (search for "Kitty"): perhaps yours does something
similar?  First thing to try is to disable auto-composition-mode.

If nothing helps, please post screenshots showing the problematic
display.
