After ~10 years of using XFCE, I recently for the first time encountered flickering, after an NVidia driver update. I disabled compositing and it went away. Still happy, but clearly something broke there. Pretty sure someone's trying to fix it, somewhere.
Also in Word etc, if I've got to spend a lot of time in a large document, I'll usually edit the paragraph body style temporarily to something sans serif. It's just better on screen.
