From Mantis:

"if I have a couple of slice views linked and try to zoom in/out using ctrl+scroll only the slice view in focus is changed. If I later zoom in using right click, all views get synced up again. I’m using the nightly 4.11.0 vesion from January 10th on linux." (https://discourse.slicer.org/t/zoom-in-linked-slices-gets-out-of-sync-when-using-ctl-scroll/9994)

This is a bug that should be fixed.

ctrl + scroll is synchronizing the zoom but not the center of the image. i.e. if I use two axial slices, link them, position the mouse on the corner of the first and perform ctrl+ scroll, only the first is zoomed centered at the mouse position.
Another example is the CT head. I want to zoom in the top of the head, I place the mouse on the very top on the Crononal projection and perform ctrl+zoom, the behavior is showed in two steps at the image below

In Slicer zoom is always around the center of the window. To look at the top of the head use the middle mouse button to pan the image. If you have a two button mouse of trackpad, shift-left button to pan.

Incorrect, if I use ctrl + mouse scroll, the zoom is centered on the mouse position.
