People talk about this issue here... And I'm a little afraid to see this happening in mine.
I don't have (yet) any issue. And I wish it shouldn't.
One question I have. The not drawing lines can be watched on the computer (what should mean that the issue is in the screen or the hard that makes this show up) or it doesn't (what should mean that the issue is in the touchscreen thing or the communication between the pen and the screen)?
