No, not at all. And I am pretty sure it has to do with the writing on the tablet. Since this was the last exchange I could do before it went out of warranty I waited as long as possible before using the tablet to write on (months and months) and the result was: no bright spots!
And when I finally did use the tablet to write on I made sure I didn't apply pressure. Sure, you need to rest your palm, but I was being very cautious! And lo and behold.... there came the bright spots again.
Only thing that may perhaps help is to pull a little bit on the screen using a suction cup. But I am really not looking forward to doing so!
I'm still just surprised that there seem to be very few people experiencing this issue.
