I just tested this with Corona 3 and Forest Pro 6.1.2 (Black Pine from starter pack) and it seems that:
-the point cloud objects are still visible in viewport when using IR
-the selection brackets are visible
Looks like it's either fixed, or I will need help reproducing it.
Update: when using IR in floating window, the objects disappear (but the bracket is still visible). We will investigate...
