#2070 new defect

Shadow glitch on cliffs opposite sun, as camera moves

Description

Noticed this on Cycladic Archipelago 6, to the south east of player 1's island with map revealed.

Moving the camera a small amount can lead to jarring changes in shadows on the cliff. In Atlas it can be more extreme with unconstrained camera, zooming out will show the shadows appear and disappear, causing a flickering effect. Unlike #2064, it's not affected by the map's post proc setting or preferglsl.

Looking for a map that exhibits this behavior now, as the originally mentioned one is gone. Cycladic Archipelago (3) is close if not identical.

Is #2953 a duplicate ?

I tried to duplicate this error but couldn't. Should I compile the code with an special flag or something? Also if I select the option Shadow Filtering in the menu then no shadow in drawn.

Replying to otero:

Shadow depends on the screen resolution, and I think problem is the z-buffer precision.
