Thank you for that link- I tried all the suggestions but can’t turn of the fade effect when i hover over the taskbar icons- I believe this is what is happening- I’ll accidentally hover over a taskbar icon, and it will fade everything- but it seems to get stuck- where all the programs or browser links etc remain faded- so far only a reboot seems to fix the issue
With linux 18.1, there is no ‘desktop effects’ adjustment or option- but there is that mapping option- I tried changing that too- but only time will tell if it works, as the problem seems ot be quite random and will happen like maybe once a week-
I’ll report it to the linux site as a possible bug-
