Short description of error
Whenever i start blender it now runs at a much lower frame rate at random moments than ever before and flashes the dark grey theme to a lighter one over and over. The entire program becomes extremely Laggy if i might call it that. Including my mouse pointer as well. everything becomes very choppy until i exit or go to another program that isn't blender. this has never happened before, it usually runs butter smooth

Exact steps for others to reproduce the error
Start Blender and immediately you will experience a drop in frame rate. the screen almost flashes from a dark grey to a lighter grey over and over and the entire program runs very slowly. doesn't matter what you do it just does it.
