Parts of UI randomly stop updating

Since the latest patch, I have noticed parts of my UI (HP/Maelstrom bars and quest tracker) randomly stop updating and I have to relog to fix it. Any insight as to why this might be happening? I did a UI reset shortly before the patch.

Try this suggestion:

I now have this issue where no matter what I do. I have uninstalled all addons, ran cvar_default, REFORMATTED my entire pc and reinstalled wow with no addons and tried steps in blizzard suggested post to no avail. What now? I have no choice but to unsub soon if i I can’t see enemy health bars…
