Bug? Panel.Height > 2046dip and panel color change to ALPHA 0

Don't know if any-one else came across this constraint,

As soon as a panel height is set grater than 2046 the background color is dropped/set to ALPHA 0 or Transparent.

This happen in the Designer and IDE (programmatically set to > 2046) Don't know why 2046, but that seems to be magic point where the reset happens).

Is this a bug or a constraint?

This is a limitation of the hardware acceleration driver. Check the unfiltered logs. You will see a warning when this happens.

You can disable hardware acceleration in the manifest file to workaround this limitation.

Thanks Erel, will rather try to split a large panel into smaller components.
