#153219 is still an issue, which I hit pretty much every day, mostly when using the Haskell extension.

Steps to reproduce:

• Hide warnings
• Introduce code which triggers an error
• Problems pane shows "No results found with provided filter criteria"
• Showing and hiding warnings again does eventually show the error

The same happens with hiding infos and introducing warnings/errors, which is the case I mostly run across. Which is to say, this issue could also be titled "Warnings don't show in the Problems panel when infos are hidden".
