Red squiggly.

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!
