It would be very nice if we can get rid of other flicker in gvim (eg.
scrolling).
I have tried twice to implement a double buffer for gvim. but failed.
MacVim will not flicker and nvim-qt will not flicker too,
Is it possible to have a non-flicker gvim ? since it's 2017 now.
Erasing and drawing directly on the screen without a back buffer
is something as old as windows 95.
