X forwarding is a pretty straightforward channel. If there's bug here, then given that X forwarding generally works for you it seems more likely to me that the bug is in the X server or X client or some incompatibility between them, rather than in ssh.
For example, I suggest that you check that your X client works properly on your X server using a direct TCP channel instead of with ssh forwarding. This would help eliminate or implicate ssh. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1533675 Title: ssh X11 forwarding has screen issue with Java applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1533675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
