Mason config TUI isn't displaying

[fkhawajagh]

I've had my nvim setup configured and working for some time. Today I tried to launch the Mason tui but the floating window won't display. It seems to be there and I can interact with it (blindly).

I'm using Lazy.vim and all my packages are up to date.

So the ':Lazy' command works and there is a floating window. However, when I use the command ':Mason' nothing is displayed. Notice the floating cursor in this screenshot.

I can scroll up and down in the floating window and even hit 'enter' to install/update package.

If I'm using split buffers and then run ':Mason' I get this weird vertical sliver of a window. I'm wondering if this is related to zindex for the floating window similar to #1787

Additionally, I can confirm the window is there by yanking lines from the invisible floating window and pasting them into another buffer.

Exact same issue here. Did you ever get this resolved?

I know this is late. But there's a quick fix. I realized that Mason TUI can be only opened when you run :only first. And then you can open Mason. For shorthand, :only | Mason.

You can also keymap it.

vim.keymap.set("n", "<leader>cm", function()
  vim.cmd("only")
  vim.cmd("Mason")
end)

I honestly have no idea why this works, but I believe it is probably a layout issue with Mason TUI. Because :only command resets the whole layout to a single grid. As if something within the layout interferes with the dimensions.
