"Main Sidebar" image on page wrong after update

Hi
After long time I made a update today.
Something changed (are now wrong), with image inserted on page via “Main Sidebar” tool.
Look herehere (look using PC-screen):

Below menu, the top image os inserted on page via “Main Sidebar” tool. This image is after update
1) “Zoomed” like crasy
2) don’t know what the point is but it is darkened by css
How can I make it look rigth (I know the “window-frame” shoud be higher to allow WxH proportions to be right) ?

Just below I have inserted the image as it shoud look with the right poportions/zoom/no-darkening.

Thanks and Best regards!
