So I was just doing random things, and decided to check out stoot's yard. While I was there, I knocked on the door for craps and giggles, even though he wasn't home, and about 1.7 seconds later saw a hiccup in the background image for the road (hiccup in this case means, the image changes for a split second, then changes back).
So I did it again, and it repeated. I then spent at least two minutes trying to use prt-screen to capture that very small fraction of a moment when it goofs up (didn't thank snapshot would do it, though never tried). So here's the visual proof in case I've done a horrible job explaining it:
Normal:
s75.photobucket.com/albums/...
The "hiccup":
s75.photobucket.com/albums/...
Opening both images in separate tabs allows for an easy back-and-forth comparison. Any further questions, feel free to reply to this post or contact me in game. If anyone else can replicate this, maybe using different backgrounds/roads, I'm sure it'd be appreciated. I just don't have the time today to go around experimenting.
Also, I scooped all of Stoot's jellisacs, because that's just how I roll. XD
