选择文本时的奇怪表现（启用了“set guioptions+=a”）

[imbear]

如图

在窗口用鼠标选择文本的时候，在之前的某个位置开始同步有个类似选择操作

去掉“set guioptions+=a”，或者去掉coc，操作起来就正常了。

自己编译的vim开发版，win10 home+msys2/mingw64：

mingw32-make -f Make_ming.mak ARCH=x86-64 GUI=yes DIRECTX=yes NETBEANS=no PYTHON3=D:/Python38 PYTHON3_VER=38 %1

我在 windows 的 gvim 上无法重现，请提供 minimal vimrc

[imbear]

vimrc

source D:/vim/bundles/vim-plug/plug.vim
silent call plug#begin("D:/vim/bundles")

Plug 'neoclide/coc.nvim', {'tag': '*', 'branch': 'release'}

call plug#end()

set guioptions+=a

gvim.exe --version

Try remove 'tag': '*' and reinstall coc.nvim.

[imbear]

删除coc.nvim目录，重新PlugInstall，问题依旧

试着把C:\Users\IMBEAR\AppData\Local\coc\extensions\node_modules下的插件都删除，操作就正常了；
再重新安装coc-yank，问题又出现了
