I heard that while public magic usage is generally banned and any trace cleaned up promptly, it's not always the case, such as when Muggle witnesses would attribute it to some more mundane explanations (eg. Lack of sleep, desert mirages etc.).
Accounting for such possible exceptions, have there been any real magic folk anywhere in the world who have openly used magic in the capacity of a performing magician, a Muggle entertainment act?
Because it is against to The International Statute of Wizarding Secrecy.
The International Statute of Wizarding Secrecy (also known as International Statute of Secrecy) is a law in the wizarding world that was first signed in 1689, then established officially in 1692. The law was laid down by the International Confederation of Wizards to safeguard the wizarding community from Muggles and hide its presence from the world at large. - Source
However...
In Harry Potter and the Half-Blood Prince, Fred and George (Weasley) visit a girl who works in a paper shop. They go there to entertain the girl with magic tricks:
"We're off to the village, there's a very pretty girl working in the paper shop who thinks my card tricks are something marvelous... almost like real magic..." —George Weasley
This is the only mention of a real wizard performing magic tricks for a muggle (in the sense you are asking), which can be taken as a "performing magician", but not in the kind of performing magician who pulls a rabbit out of a hat.
