hlint flicker on Windows 10

[EdAllonby]

Hi,

First of all, thanks for this great extension. I saw your recent Haskell Exchange talk and it was great.

hlint seems to be working, but resetting in short succession.

Using Version 0.2.2.0, Git revision 77ff1fabd5fcbd325165c40b05a5c9831937a1ee (2011 commits) x86_64 ghc-8.4.3

Steps to reproduce:

1. Windows 10 (Build 1803)
2. Build HIE .\make-build-all.bat
3. Create new project stack new --resolver=nightly-2018-09-28 test (uses GHC 8.4.3)
4. Open in VS Code 1.28.1. No other extensions installed. No customised settings.

Are there any logs which could help with this? If so I'd be happy to include them.

Looks similar to #59 and #81, but not sure if exactly the same

Logs update with the following when adding something to the file (which causes the hlint suggestion to flicker).

After investigating, I couldn't find anything in the extension that would be prematurely cancelling hlint events (in fact I couldn't find anything relating to hlint in the extension), so I presume HIE handles this directly. This seems to be an issue somewhere in HIE rather than the extension itself. Closing.
