Hello. I'm having problems with cirrus clouds. Very often there are more than one cirrus layer with the same texture. Not only it looks really bad, but at some altitudes it appears blurry and hurt my eyes.

Doesn't matter if I run some external weather application or not, if I set real time weather or theme. Sometimes it's ok, sometimes there are even 3 same layers with few hundred feet separation.

See picture:

 

May not be directly relevant, but there's a thread here which may be of interest:
