Bug#669712: freeplane: Visual corruption after scrolling mindmap right - openjdk issue?

[Omega Weapon]

Package: freeplane
Version: 1.1.3-2
Severity: normal

Dear Maintainer,

Open any mindmap, scroll right and the visible mindmap area visually corrupts. 
The mindmap seems to be rerendered on certain cues, such as collapsing and expanding nodes - 
using Tools -> Preferences -> Behaviour page -> Selection Method: Center selected nodes works around
most of the problems as using the keyboard to navigate causes the map to be repeatedly rerendered.

This issue is probably openjdk-based as it used to happen to Freemind when I used it, and in Freemind,
Freeplane and jEdit the file browing dialog's contents corrupt in a similar way. Reporting it here
as Freeplane is the program I use most by far - please say if I need to log this against openjdk.

I have attached screenshots showing the corruption, and I can make many more if needed (in the dialog's
case I scrolled back and forth a few times, the corruption seems additive).

Thanks
