When vim-airline plugin is enabled, gVim's icon on the windows status bar starts flickering as on the seen on this screencast.
gVim becomes slow, cursor starts flickering too.
This happens when vim-airline plugin is enabled. I suspect it has todo with VCS module of vim-ariline, as it also flickers (also seen in the screencast).
vim-airlinegit submodule in my.vimdir to the latest, and the issue is gone. – user3156459 May 30 '20 at 12:50
