Part of screen stops working sometimes (digitizer issue)

[Guest Sportfreunde]

Restarting fixes this issue but not always. I've changed roms after wipe (AOSP then Slimkat) and still the same issue. The part of the screen where the b/h/y keys are located usually stop working....obviously rotation allows me to press them but still concerning.

 

Is this a hardware issue or is there anything I can do to fix it (other than re-starting the device)?

a common hardware issue, the only way to fix it is to change the touch screen :S. but im not sure about that.
