<Swing Dev> How to resolve image tearing

[ximalaya]

Hi Anthony,
Good morning! Glad to know that.
Then in our case, do we have to draw texts directly in the canvas?

Regarding the different behaviour between openJDK 1.6.0_18 and latest openJDK build, seems something has been changed?

If you ever experienced image tearing or have knowledge on this topic, welcome to share with me. I've spent rather a lot time to look into this issue. For a video player written in Java, this might be a common problem. I've posted to 2d-dev mailing list, no response yet.

Thanks,
Lin
