Weird character at the end of line

[ktkimit]

I'm using alacritty for terminal emulator, and the example below is for python script (pyright LSP is used).

Some annoying character like "e" in the above figure appears at the end of line. The character does not disappear even if I close the SymbolsOutline window.

Interestingly they can also have random colors:

A somewhat bearable workaround that I have found is, <CTRL> + Z, and then fg, after that the garbage characters are gone.

I'm pretty sure this is a neovim thing, but it could just me not clearing the extmarks correctly, will have a look

bad thing happen... use :mode as work around

Pay attention that effectively very end character of a line remains

Actually, adding :mode at the end of quit action could be a fix to this issue.
