System Information
Operating system: Win10
Graphics card: Repros on both nVidia Quadro 600 and AMD FirePro W2100 cards

Blender Version
Broken: 2.80 (sub 40), branch: master, commit date: 2019-01-08 18:20, hash: 12e9d52882
Worked: 2.79

Short description of error
Lattice objects do not show up properly in Edit mode:

nVidia Quadro: There are no connecting lines between the lattice vertices
nVidia Quadro and AMD FirePro: The vertices themselves are very small (too small -- does not obey the theme setting?) and uneven (general viewport quality issue I guess)

Exact steps for others to reproduce the error

Load the attached .blend
Go into edit mode on the single lattice there
lattice.blend

It draws here same as with your second image. And this is by design, matching 2.7 well enough.

In your first image do you get any errors in the console? How about with --debug-gpu as argument?

No errors/warnings/otherwise on normal console. Attached is the --debug-gpu output though (very noisy as all pointer movements generate output :-/ so I tried to do the least amount of movement) and I'm unsure what to look for: gpu-debug.txt

This log doesn't tell much in fact. Anything out of --debug?

I think its an Multisampling Problem.

Go in the Prefs and under General->OpenGL->choose "No Multisample"

Good catch! I can confirm that this issue is related to multisampling.
More specifically, it works fine when set to "No Multisample". Otherwise the lines disappear (after a restart).

Simple gif that shows what is going on:

@fclem: When I remove the lines with MULTISAMPLE_SYNC_ENABLE and MULTISAMPLE_SYNC_DISABLE in EDIT_LATTICE_draw_scene(...), it seems to work as expected. However, I don't know what impact that change would have..
