Well, title basically. Out of nowhere everything (icons, sometime) seems to refresh, and it does so no matter what I'm doing - or NOT doing. Have tried disabling more or less everything and googled it. Google says it's due to corrupt system files...? So ran a dism.exe /online /cleanup-image /the three command line things, and then a sfc /scannow. All completed, still happening. I'd estimate the screen flickers every sayy 10 minutes or so. Has happened on two display driver versions. Any pointers?
