    JAVA interfering with graphics/full screen 3d apps

    I'm running win32 JRE1.5 u6 and whenever I have an interpreted Java program open it interfers with any and every full screen 3d application I have, especially if desktop and 3d app screen resolution differ. Symptoms include:

    Unpredictable alt-tab behaviour.
    Black screen on exiting a 3d app using a different resolution to the desktop, curable only with a restart.
    Display corruption esp. when res changing in games in instances such as playing FMV (bink, wmv etc).

    With an older set of nVidia drivers forcing AA in the driver also anti-aliased swing components ().

    Any clues or pointers on how to fix this, does anyone else have the same problems, anyone care to test, driver or jre issue?

    Just done a test and it's not just fullscreen 3d apps. It seems to be any fullscreen directdraw/ogl app whether 2d/3d, whatever.

    Done some digging and this bug report: http://bugs.sun.com/bugdatabase/view...bug_id=6213204 seems ambiguous to say the least. The Java team seems not to know who is to blame. They claim the aliased swing componets bug is still present, yet it has dissapeared in my current nVidia driver set (91.33) to be replaced with my other problems, and will be fixed in Java 6. Anyway fixes abound but most of them involve disabling d3d calls using commad line params on java progs, i'll do some digging and see if somthing more permanent is available.

    So if anyone has any of the above problems relating to their graphics, you can specify individual java apps to not make direct draw calls by specifying (using a standard -D flag) java.java2d.noddraw=true. Of course this might not be especially helpful if the application is launched by some other means (exe say).

    Or you could set the environment variable _JAVA_OPTIONS to the same (-Djava.java2d.noddraw=true).

    Here's to JAVA6.
