Here's a screenshot of a topcat plot misbehaving.
It's not very revealing, but take my word for it there should be a sky full of points visible.
I just ran topcat :skysim:1000000
from a topcat-terminal and hit the Sky Plot toolbar button. Plot comes up nicely, but when I try to drag it around using the mouse, the axes move but the plotted points go away. Note also a couple of missing toolbar icons and scrambled pixelmaps on a horizontal and a vertical divider in the plot window - those are not really a problem, but tend to accompany the plot problems.
I don’t think this is the issue (is OpenGL used?) but posting for the record : https://bbs.archlinux.org/viewtopic.php?id=269181
I'm not using OpenGL explicitly; I haven't attempted to check whether Java uses it but I would think not (there's no 3d graphics going on here). And the symptoms don't look very similar. So probably that's not the same issue.
And here's a shot of Aladin misbehaving: Icons on the left and right are scrambled, and the sky display is blank. Interacting with the plot appears to work in that the zoom slider bottom right moves, but the sky display does not respond.

Raising the priority on this as it is clear it is affecting all Java-based desktop-apps.
@ijiraq - You mentioned that you have an idea of what the issue may be. Could you please post the details so we can give it a try?
I have experienced issues with the display of java GUI applications in a science platform desktop session.
The issues are intermittent, have happened over a long period, and are in some cases just cosmetic and in other cases more serious.
Miscellaneous observations:
-Dsun.java2d.xrender=false
might fix it. But as long as it's not misbehaving consistently I can't test that.
