In GVIM I use vertical thin line as my cursor by adding following line to my .gvimrc
set guicursor=a:ver13-Cursor
This works perfectly as long as window remained focused. As soon as GVIM window lost it focus cursor change to bad ugly transparent block. How can I prevent that. (This happens in all modes like insert, visual, ...)
I'm on linux-arch-gnome3-gvim
Thanks
EDIT1
As suggested by cristian there may be a autocmd that create this effect


:verbose :au CursorLost– Christian Brabandt Nov 12 '18 at 04:12E216: No such group or event!) but I find a new event FocusLost. I edit my post and add it's response. I think creating an autocommand on Focus lost may help – pazel1374 Nov 12 '18 at 07:11FocusLost, that was a typo. Could disable the mentioned plugin and check if the problem still occurs? – Christian Brabandt Nov 12 '18 at 07:23
