There's a few aspects to this:

1. you're using the unity-ui theme. As far as I can tell, that theme has a tooltip.less file, while other themes have a tooltips.less file: https://github.com/orderedlist/unity-ui
2. the ide-haskell package is importing "tooltips", which fails if the file doesn't exist: https://github.com/chaika2013/ide-haskell/blob/master/styles/ide-haskell.less

I'm not sure I understand why the package would be importing that "tooltips" file, though. @simurai can you think of a reason for that? I think we can close this and report an issue on the ide-haskell package?

[simurai]

It looks like the ide-haskell package uses a custom tooltip and I guess tries to use some styling from the default tooltips for it.

Yes, I'll close this issue and make a new one in the package.

good catch, thank you!
