--- Comment #8 from Tobias Jakobi liquid.acid@gmx.net 2008-10-17 14:29:19 --- OK, just tried the patch and it does indeed change something.
The waterplane and sprites are now gone completly when looking straight forward. One way to bring them back (again flickering) is to look at the ground.
The 'open menu' technique still works and all looks good there.
Patch was applied on top of latest git master.
Next: Attaching trace like Austin English proposed (for this I'm going to remove the patch again).
