Usually the orbit follows the mouse, if you move the mouse left or right, it rotates the object left or right. Quite often this seems to break, and the object no longer moves left and right when the mouse moves left and right, rather it tilts the object left and right instead, this makes it very difficult to navigate. The only way I have found to fix it is to close the project and reopen it. This happens if using the middle mouse button + shift, or if I click the cube navigation in the upper right corner. In this video, it's clearly demonstrated with the cube in the upper corner. On the first tab it's working as expected, on the second tab, it's broken and no longer rotates left and right, instead it tilts left and right.
