What issues, exactly? I am using 3.5 and didn't notice anything.

The cursor jumps to the function head now and then

while editing? or while idle?

When the function is selected in the outline after editing, and it's not all the time, only now and then

I'm not sure I understand. When editing, the current function is automatically selected in the outline. Do you mean that sometimes, after finishing an edit, the cursor jumps to the header?

It feels difficult to debug without a way to reproduce...

Is this the same effect that you get when you have a long line in an erlang file (longer than the editor width) and when editing when the editor is scrolled horizontally, it jumps back to show the beginning of the row?

Yes! This might have nothing to do with 3.5, maybe it's that the outline doesn't see the difference between clicks and changes from editor.

It seems the problem is with the folding, it happens when updating the folding annotations model and it seems that there have to be at least 6-8 folding points after the long line for the problem to appear.

I give up for the time being, there are more pressing issues to debug...

Workaround: disable folding.

There is a bug in org.erlide.ui.internal.folding.DefaultErlangFoldingStructureProvider.processDelta(IErlElementDelta), when calculating modifications it exaggerates... More work needed!

Ok, this is an unfortunate one; when we're reparsing, we change every node in the model, so the folding provider thinks everything has changed. Maybe we should look into an incremental version of erlide_noparse, but not just now...
