QML camera on android via Loader

[m2dtkast]

Hey;
platform : android-29, on device.
using Camera qml object in a component instantiated via a Loader (activated when the view becomes visible);
works otherwise fine, but configuring resolution on the camera seems to not affect the size of the taken picture, which
remains the default one.
For example,
setting

imageCapture.resolution : "640x480"

will set the property, but taken pictures res still differ.

The declarative-camera example has no issues in that sense on the same device, and takes pictures in the correct resolution.

Can there be a big difference between the two instantiation ways (Loader vs static in the case of the declarative-camera example)?
