I don't really need a solution, just answer - some Swing insight. So I have a panel, and a list on it. The list is populated with strings. The problem is the following: If I add the list elements too fast, I end up with different kinds of strange windows. However, after introducing a sleep(100), or another function call, it surprisingly works fine. I didn't believe this was the problem, so I added and removed the sleep several times. It solved the glitch 10/10.
How? Why? Ideas and guessings are welcome as well.
Thanks in advance,
