Most common trigger is `xscreensaver`, but since I have set to randomly pick one, unsure whether there is a pattern. It also tends to trigger on full-screen video (display is 2560x1440 Dell 2713HM). I'm using Fedora 25, and apparently Wayland: $ echo $WAYLAND_DISPLAY wayland-0 Let me know if I can provide any more information. Thanks!
