Image previews on kitty flickers a lot.

[Aqa-Ib]

When I use kitty for image previews, the image flickers two times before currently showing on screen. I have tried with the previewer script in the wiki and also with ctpv, with the same results.
When using other terminal with sixel, the image previews are smooth without flicker.
Also, ranger do not present this problem with kitty.
I ask this because maybe I am missing something.
Thanks for your attention.
