Latest versions of Photoshop are slow during regular usage

[YahorShumski]

Photoshop become slow even when using basic instruments like clone stamp. For some reason even enabled Rulers can slow down the performance significantly. There is a lag between instruments switch etc. Too many bags to report each of them seporately.

Adobe has to test its application prior release.
