The issue still exists, as of December 2021. It appears way too often, and it's somewhat annoying as proper visualisation of cloud base is extremely important for flight preparation...

I don't believe cloud base value suddenly cuts along a straight line...
So is this going to be improved, or we have to live with it?

I don't know if it makes any difference, but tried with different graphic acceleration settings, under Chrome, no changes...

Any answer for even a slight improvement is appreciated!
