This issue reproduces in the latest OmniSharp. Any updates?

It's very inconvenient to find real warnings and errors in the list of 1207 items:

However this warnings are in ignore list in project.json:

"buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true,
    "xmlDoc": true,
    "nowarn": [ "CS1591", "CS1573" ]
}

Has anyone figured out a workaround for this? I've also bumped into it and its really difficult to spot actual errors and warnings with so much in the way!
