i installed teh Intel Open Source Intel Graphics Driver 2.21.0 update last night and this morning my gaming dekstop looked like this in games:

ltitle colored blocks, flickering lines, sometimes a whole strip of the screen goes green for a moment. it doesnt crash, it just looks horrible. my stomach dropped because artifacts usually mean dying harwdare, right? but its suspicious that it started exactly after teh update.. 🤦 how do i tell which one it is without spending money? what am i doing wrong??
