Hi Chris,
Unfortunately, the only way to make the property have an effect is to
set it before running any GUI-related code. That's because the value of
the property is being cached (see
sun.awt.SunToolkit.getSunAwtDisableMixing()).
This is made intentionally because the mixing-related code frequently
calls the Component.isMixingNeeded() method that in turn calls the
SunToolkit's one. Re-reading the property each time would introduce a
significant performance degradation.

I have an issue with the "sun.awt.disableMixing" property: when my
code is reached, I have no way to tell whether setting it to true
would have an effect.
I have such a code:
if(System.getProperty("sun.awt.disableMixing") == null) {
System.setProperty("sun.awt.disableMixing", "true");
}
but the problem is that if some Swing UI was already loaded, then
setting this property would note have any effect (that my code assumes
it worked...). I had this problem with WebStart for example, or some
other cases where some user UI was loaded before setting it. Would it
be possible that sun.awt.disableMixing be set when the Swing code
caches the value?
Better would be that setting the value would actually have an effect
instead of being ignored, but I doubt this is possible :)
