Neovim-qt: Preview window positioning and colors are all weird

[HelloKashif]

Completion window is not using correct colors on Preview (Using YoucompleteMe)
Also the position is offset

Occurs in 0.2.10 and 0.2.11, Doesn't happen in 0.2.8

It is using a native widget for the completion menu i.e. it is using the default Qt style in your system for the menu that is why the colors are different. As for the positioning it should be similar to regular nvim in the console.

We are missing a CLI option to disable the native menu too.

But this wasn't happening in v0.2.8. 0.2.8 was using correct widget and was respecting the color scheme
Seems like a regression in later versions

You can get this behaviour (let Nvim decide the popup stuff) with :GuiPopupmenu 0. Adding this in your ginit.vim should give you this behaviour.

In the following screenshots, I have

• Qt theme : Kvantum KvGlass + ArcDark ;
• Neovim theme : Snow

So anything light is from Neovim, anything dark is a Qt widget

With GuiPopupmenu (the default) :

After :GuiPopupmenu 0 :

Note that the position is not the same (above or below text here), but I still have something reasonable (this is done while working on a feature branch that only adds a directory tree view, nothing at all about the Popupmenu).

I'll admit that we can work a little bit on alignment of columns and stuff like that, but the positioning and the theming seem fine to me

@s-kashif you can get the previous behaviour back by putting 'GuiPopupmenu 0' in you ginit.vim.

@gagbo thanks I was looking that.

@equalsraf and @gagbo Thanks a lot. I'll check
