Issue: Major CPU Usage with v1.74-on
Labels: Needs Investigation

Type: <b>Bug</b>

Ever since I installed version 1.74.x, I have run into a major CPU usage issue, especially if I work on any Angular scripts.  As of right now, sitting idle, I look at my task manager and see my CPU usage is averaging around 18% for VSC alone.  And that is with all the included extensions listed below.  If I install version 1.73, with the same exact extensions listed below, my CPU usage in idle mode drops to barely 1% maybe 2%.  My initial thought was the angular language service was causing the slowdown, but I need that extension to properly do my Angular coding.  Any idea what the issue could be?
