Use lazyredraw to avoid flicking

before:

iShot_2024-05-06_12.12.41.mp4

after:

iShot_2024-05-06_12.13.28.mp4

This is especially obvious in nvim 0.10

Hey!
TBH, I've never encountered this before, the "slight flicker" I refer to is when the cursor momentarily jumps next to the INSERT or VISUAL, not that the whole buffer fllickers.
Do you know of some way I could reproduce this?

Hmm it is caused by a plugin redrawing screen when I type enter.
And these operations involve many modechanged autocmd, have you consider adding event_ignore to all?
