Description

I don't know if it's me not yet used to the new and different markers shown when digitizing but it looks like the snapping marker does not show when the advanced digitizing panel is enabled.
For example, enable snapping settings and the "Add feature(s)" tool (or "Move feature(s)" or I guess any other)
Hover over a vertex so that the marker shows (default square). Ok
Now enable the advanced digitizing panel
Hover over the same vertex. Nothing happens.

I don't remember how it was in previous releases but i'd bet for a regression...

There does not seem to be a distinct snapping marker for advanced digitizing, but there is a small X cursor that will snap to any locations that are enabled in snapping options. This cursor does tend to disappear after a certain amount of use, which may be the problem described here. I haven't yet identified what steps cause it to disappear.

In addition to the small X, there is a large "crosshair" cursor that is always present, and that does not align correctly to the point being digitized (it appears to align at its upper left corner, rather than at the center of the crosshair).

Seems also a regression to me. Tagging so until proven contrary.

There does not seem to be a distinct snapping marker for advanced digitizing, but there is a small X cursor that will snap to any locations that are enabled in snapping options.

This is the issue I was reporting, ie:
1. without the panel enabled, when you move a vertex, you have no marker (just the mouse pointer). The marker appears when you are about to snap something. And by default this marker is "magenta square";
2. if the advanced digitizing panel is enabled, you automatically have a lighter "crosshair" marker (maybe it wasn't there at the time I created the report) which is btw always displayed even at the snapping time, meaning that there's no obvious visual way to ensure you get the catch (like the square marker does in the previous case)

This cursor does tend to disappear after a certain amount of use, which may be the problem described here. I haven't yet identified what steps cause it to disappear.

I can't reproduce the disparition issue.
