Saving to EXR or HDR fails for this scene?

On my side when compiling and using Malia on master branch the attached scene can be open and displayed interactively (malia -i) but when saving the generated images cannot be open by SpectralViewer (3.0.1b) or even exrdisplay for .exr files.

Another weird thing is that the image is supposed to have 1080 = height 1920 = width pixels but it is the contray that is displayed when using SpectralViewer or display or exrdisplay

Can you confirm or deny this behaviour?

Cheers R. PS: The same malia version works with Official CornellBox sceneshapes_on_plane.zip
