Strange pictures for strong winds

[idefix37]

For one or two days I have strange artifacts for winds of about 100km/h or more.
Here are Leslie and Michael hurricanes with GFS

It changes with the zoom level.
Is it due to my personal settings of winds?

Have you tried to turn-off the "show lat. lon. grid" in the settings?

I’ve just done it. It does not improve the wind distribution beyond 100km/h.
You don’t observe any similar issue on your side?

No. Everything seems OK
