I'm not surprised. The "weird dark pall" has been #1 on my list of FG bugs for months. The bug is known to be shader-related. The bug is quite serious; the sim is unbearable to look at with shader-effects turned on. I have observed this equally with Debian Squeeze and Ubuntu Karmic. > Does anyone on the -dev list have an ATI card that is working (or > not) with the shader options? I have a Radeon HD 4870 with 1GB of 256-bit GDDR5. It uses the RV770 chipset. I've run a sampling of tests from the phoronix test suite and never noticed any problems. FG is the only application that suffers from either the pathetically low frame rate or the shader-related pall. > Are you seeing any error messages in the console at all?

The details of the pall seem to depend on time of day (angle of sun?). The pall depends very stronly on direction of view. For some directions, the pall is not noticeable, but panning the view a tiny amount brings the pall back in full force. =============== As a tangentially-unrelated remark: no matter whether shader-effects are turned on or not, I observe that the /sim/rendering/random-vegetation property has no effect. Is it obsolete?
