I found something using Logi Options+. When using a dual monitor setup I noticed that the Logi Options+ on screen notifications (Num lock, Scroll lock, Caps lock , Backlightning ) are not readable on the secondary display when working on that display. See the attached screen dump. The notifications on the main display are displayed correctly when I am working on the main display. I use the Logi Options+ version 0.42.692
