Strange corner glows.

[adomolis]

Hello Community,

Here's the problem. My wacom cintiq (DTI-520) was running like a charm until one day I turn it on and it gives me those strange glows in upper right corners. The longer it stays turned on, the brightier they become. Anyone has a clue what could that be?

Thanks.
