I recently purchased a T440s with FHD touchscreen. I'm running Windows 8.1 and observing some screen burn-in / ghosting / image persistance. What I mean by this is the following. Suppose I have a window open (e.g., browser window), and leave it open for some time (e.g., 15 minutes). When I minimize the window, I occassionally still see a faint version of the previously maximized window which persists for a while, and eventually goes away. This leads me to think my display might have issues. Is anyone else observing this?
I have Intel HD Graphics 4400, and I'm using driver version 10.18.10.3412. I see that there are newer 4400 drivers available on Intel's website, but I'm hesitant to go that route because I haven't seen any other people with this issue so it makes me think that it's not a driver issue.
