Flickering on ATI Mobility FireGL V5200?

I've upgraded a JOGL 1.1.1a application to the recent jogl-2.0-pre-20100517 build. I'm using the Windows i586 build.

The application has the same 1.1.1a settings in terms of double buffering and VSync, but it now shows flickering black bands across the expected output.

I've tried using both AWT, as well as NEWT, but the result is similar.

From what I could tell from the available on-line demos, e.g. Gears, the problem is visible for those applications as well, on this particular development platform.

However, the application in question and the JogAmp Gears demo do run properly on a different platform, which uses an NVIDIA GeForce G210M graphics subsystem.

Is this a (minor) issue of compatibility with the ATI Mobility FireGL V5200 driver?

Is there anything I can do to help resolve this issue?

So it's not related to the AWT clear background thingy of a Canvas, good.
This is proven by your NV test as well, right.

I use
GL_RENDERER   = ATI Radeon HD 5800 Series
GL_VERSION    = 3.2.9756 Compatibility Profile Context

on linux 64bit here, no flickering.

The gears demo uses:
        gl.setSwapInterval(1);
which works here (VSync 1), but I have noticed that
the drivers behave differently in overwriting the default setting.

IE I had to set (fglrx 3.2.9756) VSync: 'Off, unless application specifies',
otherwise I couldn't turn it on or off.

Don't know the windows driver settings, sorry.
