Shear in 2.79 and 2.80 not working?

I have a Problem with Shear transform Shift+CTRL+Alt+S
i cant set the axis. When i press x or y nothing change.

In 2.79, shear is pivot and view dependent. Also as with any other tool and modifier, unapplied object transforms can affect how the tool seems to behave, as they operate in object data level.
