[BUG]: Winbar appears, flickers then disappears

[willothy]

Requirements

• [X] I have scammed other issues to see if this bug has already been reported.
• [X] I'm fully certain that this is not a breaking change, see the latest release.
• [X] This plugin and its dependencies are up to date with the latest commit.
• [ ] I'm willing to fix this through a PR.

Expected Behavior

Winbar should stay on-screen as shown in the example gif

Actual Behavior

Appearing then disappearing: https://user-images.githubusercontent.com/38540736/218783030-be32e4ee-4651-4d96-9e0f-e4fedd4f035a.mp4

Flickering (only seems to be visible when cursor is moving) https://user-images.githubusercontent.com/38540736/218788089-c6652569-fd53-492e-9e4b-842defdd8084.mp4

Minimal Configuration

end

--   -- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"

Reproduction

1. Start neovim
2. Start editing nvim configs
3. Barbecue flickers on and off or just disappears entirely

[utilyre]

That is not a minimal config. A minimal config is supposed to be run like nvim -u repro.lua and should reproduce the given issue. The one that was given by default is a good place to start.

[willothy]

Sorry about that, I didn't realize that was used for more than info. I'll update the config to be usable.

I would also be open to trying my hand at a PR if it turns out to be a bug, just wasn't sure I should lead with that as I'm new-ish to neovim/open source.

[willothy]

Ok, my bad again this was a config issue. Barbecue was conflicting with lualine's winbar, even though the lualine winbar entries were all set to empty. Removing the lualine winbar config entirely fixed the issue. I'll update the report with the repro file anyways, but feel free to close.

[utilyre]

Glad that it's been fixed :).
