Type: Performance Issue

I am having issues with visual studio code since a few days. It is pretty slow. By checking the activity list i see the code helper (Renderer) is ramping up very fast to over 100% CPU.

I already disabled all extensions to exclude an issue with same.

Any suggestions?
Maybe i try downgrading a version, i guess this is since the last update.
