I maintain a few NUC's (of multiple generations) and one of the final hurdles all of my users report is a slight flickering when updating tasks and events in Gnome Evolution.
Usually I install xserver-xorg-video-intel on all my machines and was under the impression that the intel DDX driver was causing this flickering, so I removed it to see whether the modesetting DDX driver would improve things. It didn't, but as it turns out: reinstalling the intel DDX (and adding a Device section to xorg.conf.d/20-intel.conf) does not make Xorg choose the intel DDX driver...
How can I disable/blacklist/block the modesetting DDX driver?
