Invalid 3d rendering on macos big sur

Hi

I have installed the latest version of Adobe Reader DC (2021.007.20099) on macos big sur 11.6.

It is a macbook 15.1 (2018, Radeon Pro 560X).

The rendering of a 3d annotation is incorrect. The viewport has half the size it should have.

The same version of Adobe Reader DC on the same machine works fine on macos mojave 10.14.

I think the problem may come from how retina displays are handled by the Reader on 11.6.

I put here two images  to show you the expected result and the issue.
