You will have to post more detailed steps on how to reproduce and what result you expect.
Just using loop cut and slide on the default cube doesn't seem to do anything with or without the Even option and alt+mouse wheel.

The possibility or option of being able to change "control edge" with the keyboard shortcut "Alt + Wheel mouse" during the execution of the operator "Loop Cut & Slide", and more specifically with "Even" activated, always existed and always worked in version 2.79 and earlier of Blender, both in a simple cube and in any other more complex 3D model, and it is very useful to achieve that the shape of the cutting loop has more or less travel in its slip according to the "edge" of control "chosen.
This option is simple, and does not require certain steps (more than the activation of the "Even" option) in the course of the operator, nor does it depend on any circumstance or specific context (rather than being in "Edit mode" and acting on a mesh) to work or not work; and it just does not work in Blender 2.80, or at least it has stopped working with the shortcut that continues to be reflected in the user manual of version 2.80:
https://docs.blender.org/manual/en/dev/modeling/meshes/editing/edges.html#edge-slide



In Blender v 2.79:

… In Blender 2.80, simply doesn't work the shortcut "Alt+Wheel mouse" with the option "Even", while attempting to perform the sliding of the cutting loop

As an extension of the problem, the referred failure occurs not only in the operator "Loop Cut & Slide", but also with any other operator that executes a sliding of vertices or of edges along other "control edges" (as per example: with the operator "Slide Vertices (Shift + V)" or the operator "Edge Slide")-

Could it be that Blender 2.80 has been provided with a different keyboard shortcut? ... In the "User's Manual" of Blender 2.80 it is written "Alt + Wheel".

I've tried just re-enabling and this seems to work without issues:

Re-enabling and testing this feature, I realized that it does not work properly with multi-objects. Because the cycle between the reference edges is repeated only in the active mesh.
The expected would be to jump to the other meshes.

But in my opinion, although it is practical to use modal keymaps to change the behavior of a modal operation, this large amount of modal keyitems does not seem to help much, it does more to complicate learning.

Also, the fact that the chosen reference edge is the one that is closest to the mouse cursor is, in my opinion, already obscure.

With that in mind, instead of re-enabling this feature. I would prefer:

  • Remove these modal keymaps;
  • Make the reference edge always to be the one with the vertex active.

Didnt have the expectation :) But yeah, if this has problems then the modal keymap, should probably (at least temporarily until the feature is back) go as well

Make the reference edge always to be the one with the vertex active.

Is this clearly defined? sliding an edge, what is the edge with the vertex active?

In fact, it needs to be better defined.
I would like to avoid depending on the mouse position, but since multiple edges can have the same active vertex, perhaps the position of the mouse still needs to be used.
The main idea is to avoid having to use Alt + Wheel to choose another edge.
And relying only on the mouse position does not seem to be ideal.
