possible Crystalis graphics bug

[Xenos]

Hello. I am using the latest version of JNES and I am wondering if the following issue is a bug. When I load the "Crystalis (U)" rom I get a weird graphic issue. Whenever I talk to someone, the screen shakes slightly, as if an earthquake is happening. The graphic issue is not the one talked here at this thread: http://www.emutalk.net/showthread.php?t=29861&highlight=Crystalis
I have tried the same ROM in VirtualNES and the shaking is not present. Even with the selection of multiple roms to test, I still get the same earthquake visual bug. Any ideas?

I took some screenshots to show what I am talking about. The "bad" screen has several "B" letters in lower left. These also show up when talking to people in town.

I wonder if others could try it to see if they can reproduce the error, perhaps even the JNES developer can look into it as well.
