I guess it is a better description of the flag. A flag should flutter in the wind, and so does this one here. I wouldn't judge its correctness because I am not competent enough. I personally prefer a fluttering flag to a signboard flag. :happy_8:
The way it is fluttering, even horizontal strips will be horizontal. Can never imagine how fluttering can produce slanting strips. If it is built in feature, even then it can be got corrected. This animated giff has 18 frames, all slanting strips.
