Export Plot including Img (Issue with scaling)

Hello

I want to export a plot that displays an image and some vectors:

imshow(Img);
alpha(0.8);
zoom off;
quiver(point(:,1), point(:,2),disx(:)*M,disy(:)*M,'AutoScale','off','color',[0 1 0]);
axis on; xlabel('U [px]'); ylabel('V [px]')

For export to .png I wanted to use the Export Setup to define: size, font size and resolution (etc.).

The appearing issue is:

When scaling the Plot down to e.g. 15cm width the axis labels get cut off horribly.

The Issue only appears when plotting the Img. Normal Plot e.g. only quivers works fine.

Expectation:

vs.

Reality:

Somebody can help me?
