I usually uses ECMWF when viewing forecast in windy.com, but recently I use GFS for comparison, and there is a mismatch between wind speed contour and vector (image attached for Aug 4, 2017 GFS prediction over western Pacific Ocean SE of Japan). I uses the newest version of google chrome (WebGL enabled) in Windows 10 environment.

GFS wind data problem.
Snow accumulation indicator error
Snow accumulation error...
This bug is appearing randomly, but usually after setting a new accumulation time / set zooming / or clicking a random region after dragging the flag (which was behaved normally). The pattern is "work normal - set new zoom / accumulation time / re-click a region - drag the flag - abnormal behavior". Thanks for your concern.
