preview-tui - prevent images from flashing while scrolling

[willow-sprite]

I'm not sure if there is an obvious solution for this somewhere.
I couldn't find one in the issues or discussions.

when I scroll through a directory of screenshots for a game, the images disappear & reveal the background for a bit before loading the next image, leading to a flashing effect that messes with my vision.

is there a way to keep the previous image loaded until the next one finishes loading, rather than showing the terminal background for the time inbetween?
or should I make this a feature request?
