Annotations got messed up when switching between photos

Hi,

I didn't find any report on this, but on C1 15.3.1.15, MacOS 11.6.7, when I'm drawing some annotations, switch to another photo and came back on the annotated one, then annotations are rotated by 90 degrees.

Do someone have observed this already, and got a solution? 

Note that I've made a video screenshot but cannot attach it here. 
In case there is no workaround, I will open a ticket.

Best Regards,
Sébastien
