Java2D guys -> EventQueue deadlock

Java 2D
#1

At least one paint event seems to make it through a cycle as I do see one frame of animation but that is it. The bug database seems to be down or I would look for a dup. Any ideas java2d guys?

I don’t understand your post. :frowning:

You’re getting a deadlock, but you can’t figure out why? Do you have any code snippets or an explanation of what you are doing?

Cheers,

You’re apparently using jogl, wouldn’t it make sense to ask on JOGL forum? I don’t think it’s a Java2D related problem…
