I've been using my 7" display for a while and love it.
Since I updated to Stretch (yes, I know...I'm behind the times) the top ~1" of the display won't recognize touches. The display works fine and, if I connect a mouse it'll work fine. Looks like it's the input itself that's not working.
The worse part is, I had this problem before and don't remember how I fixed it.
Is there a software config anywhere for the size of the touchscreen or is my hardware hooped?
