Atom unresponsive for 4-5 seconds when switching between atom and chrome


I do not know what happened, for months it was running fine and I had no delay like I experienced today after win10 updated. Project is using git and its big project, but that has not changed since 4-5 hours ago when I was running it without any problems.

here is video of delay in action:

how can I restore the atom to its previous speed? I am running 1.18.0

It could be this problem:



I had the problem also when I did not have a git project opened. Not sure what happened but there is no delay anymore, not even 1 second, when I switch back it is available for typing right away
