--- Comment #10 from Fabio Pedretti fabio.ped@libero.it 2011-01-25 08:49:19 PST --- Created an attachment (id=42472) --> (https://bugs.freedesktop.org/attachment.cgi?id=42472) sauerbraten screenshot with second patch
Note that the clouds appears mostly when moving your player. When he's stopped they are smaller, fewer and mostly only visible near edges, like a light that's entering from the outside. The attached screenshot was taken when moving the player (the tearing line you'll see is because of this, probably the screenshot included data from two different frames).
