i own a 7" RPi Touchscreen and mounted the RPi2 at the back of the Display. Actually i run the Combo standing on the Touchscreen-Glass leaning on a Cup while installing Gentoo. The Display was several Days on and get hand warm on operation.
I Experience now that the Display behind the TouchScreen-Glass skewed a little down. The Glue between Display and TouchScreen seems to retreat.
Does anyone also experienced this behavior?
