I haven't landed on a planet a few months but last I checked it worked fine. I'm assuming it's a video card driver but I updated to the latest one and the problem still exists so I'm wondering if it's an Elite bug.
Look at the ground in front of the SRV in this video:

I'm on Windows 7 x64 with an EVGA GTX 970. I was using the 373.06 driver when I realized the glitch was present. I updated to the 378.49 driver and the problem still exists. I'm going to uninstall the driver and go back to something prior to 373.06 this evening when I have time to see if that helps.
