IntelliJ breakpoints freeze gnome

openSUSE 11.2 (x86_64)
2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03 +0100 x86_64 x86_64 x86_64 GNU/Linux

IntelliJ 9.0 and 8.1.3

Hitting a break point reliably freezes the entire Desktop. Only the mouse is at all responsive, in that I can move it around, but no clicks are accepted, no keystrokes work. Except C-A-F1 etc, which I use to kill either the app begin debugged or intelliJ itself and then gnome Desktop is happy again. Furthermore which ever one I didn’t kill is perfectly functional.

I use focus-follows-mouse, compiz. Java 1.6.

This behaviour just started recently. Yesterday, in fact, and that’s when I moved from IntelliJ 8 to 9 hoping that would fix things.

I’m up-to-date with patches.

As per instructions from Alexander Chernikov [Linux] Stopping on a breakpoint can cause X Window system freeze :: JetBrains Developer Community](http://www.jetbrains.net/devnet/docs/DOC-1142)
adding ‘-Dsun.awt.disablegrab=true’ to the VM args cured the problem.
