Hi altitude vertical lines

[K2mil]

Hello All I noticed these lines when I fly or watch other planes fly above 14K feet Please take a look.

 

Edit: It's not usual thing but when it appears its over the sea I'm pretty much sure it has to do with cloud shadows and I only notice it at that high altitudes where I don't fly much in a 10c but it makes me concern for future jet modules.

 

Edit 2: it's a know bug http://forums.eagle.ru/showthread.php?p=1728929#post1728929
