I have the same problem. It's been acting up for about a month. I've had it for 6 months. I *think* it was better before but it could be that I'm playing more games now that use more of my play area. Honestly not sure. I just know that at the beginning I didn't worry about this at all and now it is a constant problem and is ruining everything. I can't even defend the castle in theLab without a couple of whiteouts.
Two days ago a guy talked me into trying the sync cable and it did not help.
Like Aidarpro said, mine seems to get worse the longer I play. I'll move a base station, run room setup, then I'll be testing it out, thinking everything is cool, then as soon as I start getting "Immersed", BAM, I see white and its back to harsh reality. Like today I was just playing the Wave and I was really getting into exploring the universe and I got a flash, the some more, then by the time I gave up it's like it had its mind set on not letting me look in exactly the direction I need to look.
I don't know how to proceed. I would gladly buy another base station if it could use three just to eliminate the bad spots. Even defending the castle from the hoard I have to remember where the guy was and take my shot blind and hope it comes back. Somtimes when it whites out, I'll peek out and I am staring stright at a base station. :mansad:
