Thanks for the report. I'll take a look

@wuqiong4945 Sorry for the long delay.

I am not able to replicate the issue. Do you still have the issue with the latest version?

Which keymap is this? u or U or something else?

[ryanoasis]

@wuqiong4945 Ah okay now I see it. It is with U (uppercase U)

I have encountered this bug, initially in a different way but I also tried by pressing u and it still happens.
Here are the steps that reproduced the issue for me:

1. Navigate inside a folder by pressing e
2. Move up entering the parent folder ../ with <CR>

I have also noticed that the behaviour is different depending on whether let g:DevIconsEnableFoldersOpenClose is set to 0 or 1.
In my recording above, I have set it to 1. When the issue occurs, the icon gets fixed by cycling open/close status for the particular folder. If it's set to 0, instead, cycling open/close the folder doesn't fix the appearance.

@ryanoasis I am having this problem even now.
Reproducible just by

1. start vim in a folder
2. toggle nerdtree and
3. press 'u'/'U'

This only happens the first time I go to the parent dir, e.g. press 'u' when first time open nerdtree or after I jump to a bookmark.

Tested with a minimal .vimrc below and on Archlinux, urxvt, vim 8.1, Hack nerdfont and plugins fresh installed.

.vimrc:

call plug#begin('~/.vim/bundle')
Plug 'scrooloose/nerdtree'
Plug 'ryanoasis/vim-devicons'
call plug#end()
