Annoying auto-linter rendering workspaces unusable

[ScrewTSW]

Describe the bug

Affected devfiles:

• Java Spring Boot https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/java-web-spring
• Java with Spring Boot and MySQL https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/java-mysql
  EDIT:
• NodeJS Angula Web Application https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/angular

Cursor is being spastically moved around during use, rendering the devfiles unusable (super irritating, rewrites what you're typing, messes with code)

Che version

• latest
• nightly
• other: 7.13.x

Steps to reproduce

• Start any of the two workspaces
• Open any file and wait for the LS to initialize
• Try to write any code

Expected behavior

• Linting doesn't happen automatically on it's own, especially not while typing

Runtime

• kubernetes (include output of kubectl version)
• Openshift

Client Version: 4.3.9
Server Version: 4.3.0
Kubernetes Version: v1.16.2

• minikube (include output of minikube version and kubectl version)
• minishift (include output of minishift version and oc version)
• docker-desktop + K8S (include output of docker version and kubectl version)
• other: (please specify)

Screenshots

Installation method

• OperatorHub
• I don't know

Environment

Unless this is an intended feature, I was still able to reproduce this on both workspaces

[ScrewTSW]

Still true for 7.16.0

The issue is newly present on the NodeJS Angular Web Application stack as well (link)
