Owner

In edit mode, holding Ctrl+Shift (or choosing Stretch in the Build floater) should show the scale handles: the corner and face boxes on the selection's bounding box, used to resize the object. They don't appear.

To check

Whether the stretch manipulator (LLManipScale, llmanipscale.cpp) is active and only failing to draw, or not activating at all. Test: does dragging where a handle should be still resize the object?
Drawing: under Vulkan, the manipulators draw in the world-overlay pass (uiRender in llappviewer.cpp calls renderSelections against the world depth). Check that LLManipScale::render goes through that pass, and look at its depth test / LLGLDepthTest and any bindManual texture use. bindManual is a no-op under Vulkan; see #144 and #148 (the move tool's snap grid) for the same class of bug.
Compare with the move (translate) and rotate manipulators, which draw. The difference between them and scale points at the cause.
Whether scale is gated on a render/debug flag, or on the UI feature bit, that Vulkan never sets.

Related: #148 (move tool snap grid not drawn), #101 (builder views).
