In and out of build mode there are floor glitches, when you are on any floor level that is not the main, visuals are constantly glitching in and out of focus rapidly, making it really hard to look at. You have to play around with the camera a bit to avoid this by keep your screen at a different angle.
wambat222 Would it be possible to post a video of what you're seeing? I'm not quite sure what's going on just from your description.
Please also provide a dxdiag, for reference. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
