Mouse cursor flickers while moving around (all programs)
This problem started up about a month ago now. Basically the cursor starts to flicker at random while I move it around the screen. It doesn't fly all over the place as I've read other people's has, but it's pretty annoying and I can't figure out why it's happening.
At first I thought it was just happening in my internet browser (I mainly use Chrome) when I hovered over links, but now it happens in most programs. It makes using Adobe Illustrator (I do some graphic design) very difficult because I can't see the contextual icons telling my what I'm hovering over.
It's also very random when it happens. It doesn't do it over every link and sometimes it will do it only after I click on one. Sometimes it will do it just as I move the cursor around the screen. In Illustrator, for instance, it does it pretty much constantly.
My software is up to date, and I haven't been able to find anyone encountering the same issue as me. Restarting doesn't make it go away, any thoughts?
