Glad to know there is workaround.
I launch Quartz Debug and mark the radio button
"Disable Beam Synchronization". Now my application works well, the
refreshing problem has gone. Then I quit Quartz Debug and my application's
problem occurs again. I launch again Quartz Debug and strangely the radio
button "Disable Beam Synchronization" is not marked anymore.


How to set it permanently? And, most of all,
do I have to say to all of my clients to do this settings by themselves?
I hope no.

Quartz Debug resets the mode to "automatic" when it quits. The Window Server debug state is global for the session, not per-process or per-window. If your app disables it, it should re-enable it upon quit; you should present a warning dialog to the user and let them make the decision. Here is the necessary code:


    extern void CGSSetDebugOptions(int);
    extern void CGSDeferredUpdates(int);

    typedef enum {
        disableBeamSync = 0,
        automaticBeamSync = 1,
        forcedBeamSyncMode = 2
    } beamSyncMode;

    beamSyncOption mode = disableBeamSync;

    CGSSetDebugOptions(mode ? 0 : 0x08000000);
    CGSDeferredUpdates(mode);

All disclaimers shall apply.  ;)~
