Hardware accelerated scaling on external display not smooth since 11.0

Question

Hi,
When running 1280x800 app in fullscreen mode with hardware accelerated scaling (fullScreenSourceRect) from a laptop on the second screen (extented desktop etc)  hardware scaling seems to fail to smooth the image on certain cases.
flash version
screen resolution
result
10.3
any
works
11.0 - 11.2
1280 x 1024 or 1280x800
works
11.0 - 11.2
any other
fails
We're actually making an Air app, but it seems flash player has the problem and air 3.2 comes with flash 11.2.
Code for fullscreen:
stage.fullScreenSourceRect = new Rectangle(0,0,1280,800);
stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
Here's a list of display adapters we've confirmed the problem with, but it seems there's others too:
Intel GMA X3100
Mobile Intel(R) 965 Express Chipset Family
Mobile Intel(R) 915GM/GMS,910GML Express Chipset Family
Anyone have any workarounds or other advice for this?

You can also try booting into the Safe Mode to see if the problem is there also.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.
