Empty ImageJ windows under Ubuntu with compiz

[Michael Doube]

Hi all

Compiz is the whizz-bang eye candy that Ubuntu uses with the GNOME desktop environment.

When I enable compiz, I sometimes get empty windows with ImageJ: these can be image windows or plugin windows (like W&L for example).  Closing and opening the file / plugin a few times can restore functionality.  Using no eye-candy (compiz disabled) also restores normal functionality.

Has anyone else seen this, or is it peculiar to my setup?  I'm not sure where to aim this bug so I've started here; it could just as easily belong to Sun's JRE, compiz or GNOME so please let me know if you have more insight than I, and I'll file the bug in the right place.

Cheers

Mike

IMO it's a compiz bug related to java apps -and no others, which hints
at problems with the gtk that java uses.

So far I've seen this behaviour in ubuntu machines that run with nvidia
cards, only when compiz is enabled.

I think most of the bugs between Compiz and AWT belongs to the AWT  
implementation and how it draw the components.

One fix for some problems is editing the /etc/environment and adding  
the var:

  AWT_TOOLKIT="MToolkit"

I remember that nasty bug  but I think I didnt find a fix :( (except  
than disabling compiz). I used the opensource ATI Radeon drivers, but  
I bet the problem is the way AWT components are drawn, may be the last  
version of the JVM fix some problems (I tested long time ago with JDK  
5).

If you have more information that can help the developers please post it
there.
