fglrx 8.3 freezes in 3D apps @ 1400x1050

[madman2k]

If I set the resolution to the native resolution of my LCD(1400x1050) all 3D Apps freeze as soon as I enter the game. (curiously it does not freeze in the menu). This does not happen at any lower resolution or if the window is not fullscreen. The Hardware is a M66GL(X1400) with 256MB of VRAM.

Is this a known problem? And if not where to report to get it fixed?

I have not seen a resolution-specific 3D hang mentioned before. Anyone else ?

The best way to report the issue is via the community Bugzilla at :

Are there any suspicious messages in your logs ?

the only suspicious message I've found is this in syslog:
