Hot damn! That worked. I didn't have to use Ewmh. Just set the WMName to LG3D. Thank you! On Sat, Nov 3, 2012 at 12:49 PM, Brandon Allbery wrote:

Without restarting X11, I did xmonad --recompile and still see grey screens when starting Java apps.

Last I'd heard, recent Java 7 was still broken in some way that ICCCMFocus can't fix. But ICCCMFocus only addresses focus issues, not gray windows; that part is generally dealt with by forcing the window manager name to one that is recognized as non-reparenting, to turn off a bit of questionable design in the JVM. (I had been under the impression this wasn't necessary in Java 7, but I don't know for certain.)

That said, try using EwmhDesktops (which adds in the known gray-window fixes automatically) or adding (setWMName "LG3D") to the StartupHook (or myStartupHook in your config).

Actually, I forgot to mention, I tried your solution with Java 7 which didn't work. I had to downgrade to Java 6. I can't conclude that they still have a hardcoded list. Yeah, another mismatch between standards & practices. Hooray! On Sat, Nov 3, 2012 at 7:45 PM, Brandon Allbery wrote:

That's interesting; I had hoped they'd moved past that hardcoded list. :( On the other hand, there is only one standard protocol I'm aware of that exposes the difference between reparenting and nonreparenting window managers in any way, and even with EwmhDesktops we don't support it. (And that's not its real purpose, so if we obeyed the protocol things might still be broken.)
