Why this double dimming with fzf-lua?

[samuelsimoes]

Hi guys,

I am using the vimade and loving it, but for some reason when the fzf-lua window opens, I see this "double dimming" in the background. Do you guys know what it can be? My vimade config is the default one and my fzf-lua configs are just keymaps.

Hi @samuelsimoes, good find! I also use fzf-lua and had never looked closely enough to see this happen:D

There are a couple things going on:

• fzf-lua uses a separate backdrop that applies a second dimming effect. If you don't want this you'll need to either disable the backdrop for fzf (fzf.setup({winopts={backdrop=100}})).
• A delayed dimming effect occurs because fzf-lua has eventignore around the window open: https://github.com/ibhagwan/fzf-lua/blob/main/lua/fzf-lua/utils.lua#L1133 . IMO win_open, set_buf, etc shouldn't be wrapped in eventignore. Maybe the author will accept a PR on those as the behavior doesn't look configurable.

Using filetype as a trigger event also should work for the time being:

Example to fix:

fzf.setup({
  -- other config options
  winopts = {backdrop = 100}
})
vim.cmd {cmd="au", args={"FileType fzf call vimade#DeferredCheckWindows()"}, bang = true}

This worked perfectly!! Thank you!
