It is a great pleasure to comment on this known and quite common problem. (In other words: 1 trick of an adjusted coordinate.*) If it persists it many help turning the display upside down or, even better (improved blood circulation), try a headstand in front of it. But be careful with numbers such as 9 and 6... Hope we get the former glamor back to the list!
