Dear David, maybe it is an issue with my computer (memory corrupted, wrong OS, ect.) but the problem continues to be "randomly" present. Randomly because if I close and open the application the clouds look well and after a while (maybe after a new download or after loading again the data file) it looks like in the small video that I am sending to you.
My OS is windows10 home edition.
I thought you are interested to know.
I will try it in another computer and I'll be back.
Regards
Gian
