Toggling buffers with mini-animate loses transparency for several seconds

Here's a video to show what I'm describing:

Is there any way to prevent the black background from showing up for several seconds? When I disable the plugin, I don't have this issue.

Unfortunately, I can't see a video. It says "No video with supported format and MIME type found". Probably, because I am on Firefox. Could you try mp4? Nevermind, I can see it now. It looks like my next point still stands.

But even before doing this, do you have window animation turned on? By default, 'mini.animate' animates window opening and window closing. Does disabling them help? You can do by incorporating these config options:

require('mini.animate').setup({
  open = { enable = false },
  close = { enable = false },
})

They by default use winblend option of floating windows, so they should look like gradually fading and be barely visible. Look at demo towards the end.

Yep, this worked. As I'm using LazyVim, I just put that statement in the lazy file.

@echasnovski Thanks for the clarification. I also encountered this problem. Is it possible to make the current animation compatible with transparent background? I'm not sure if this feature request makes sense, since winblend is designed for a "fading" effect, which may not apply to transparent background...

[echasnovski]

It is possible to animate using window effects with gen_winconfig and adjust winblend option to be constant. Here is an example.

Another approach might be to set MiniAnimateNormalFloat highlight groups to not have transparent background. Not sure if that will help, though (can't remember and it might depend on how transparent background is set up).

But my personal suggestion would be to disable open/close animations altogether if you use transparent background.
