Thank you guys, in particular darkangel2154!
I was horrified when I tried to update my graphics drivers recently and got hit with a boatload of stuff I didn't ask for.
In previous AMD graphics driver packages there were options which allowed the user to ditch unwanted features. I expected this to be retained from previous versions and felt violated when these features were crammed into my system without prior notice or consent.
After spending some frustratingly ineffective time looking for a way to disable the stuff I didn't want to use and discovering that all I could do was disable hotkeys, I decided to give it a few days and see if it worked ok.
However, I experienced weird freezes when changing between my game in a fullscreen window and other windows on other monitors.I assume that some feature that is meant to permit control of game graphics behaviour or provide an overlay which I don't want is messing with my cherished ability to smoothly swap between game, voice chat, browser (not edge) and other windows.
While this weird half second delay before the windows update again on change has been annying me for a few days, today I decided it was enough. After reading this thread, I ditched the junk and installed only the extracted driver. And...works like a charm. No brief freeze when alt-tabbing or moving to another window with the mouse.
I run three fullHD displays on a R9 390, which worked fine before the bloatware attack and works fine now again without the ballast.
