Windows 10, Metashape v1.8.4, 1920*1080, no modification from OS (set 100%).
The flag circle is small and it's ok if I need to see only. But if I need to move it on the exact position is not simple to center the arrowhead in the little cirlce. I there isn't a trick that I don't know (and it's probably.....) it would be useful and much faster for the circle to get bigger if the arrow approaches a certain distance (by setting a threshold outside the circle).
I used my Metashape on my Lenovo laptop, resolution is higer and all is more detailed (but smallest......).
