When selecting ICON and Accumulation wind, I get this type of picture. There no similar problem with Gusts or with ECMWF and GFS.
The way how the image is « broken » depends on the zoom level.
I get it on OSX and iOS devices.
@idefix37 Yep, you are right. @TZ will have look.
Note: the same happens with NAM
@idefix37 Hi, this bug has been fixed! :)
