What's the problem? Describe what went wrong in few words.
A particular effect is emulated incorrectly: several objects like runeys, direction arrows, and others show "ghosts" copies of themselves near them.

What did you expect to happen instead?
I'm fairly sure the copies shouldn't exist.

What steps will reproduce the problem?
It seems to be a common bug, at least another user has noticed it (see the forum thread), so you should be able to notice it as soon as you start to play, going to the right of your house toward the barn (the screenshot should clarify that)

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-1904

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
As far as i know it has always been there, even with older versions.
I played this game 2-3 years ago and it was there.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Phenom II x4 955, Windows 7 x64, ATI radeon 5770, 4 gb RAM.

Are you using the 32 or the 64 bit version of Dolphin?
64 bit version.

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
