XF 1.4 Member tabs jump around...

I have a few new add-ons that add new member tabs, and one of them now "jumps around"
Honestly, can't explain, best to simply view video:

What are my options to fix this?
Any ideas?

You will need to contact the add-on developers for support.

@Brogan
When I minimize my browser, it affects xenforo tabs as well, not just the add-ons.

Further more disabling the addons adding tabs doesn't fix it.
Xenforo tabs are still broken on a minimized browser.

It's a style issue then.

It doesn't happen here on the default style.

Ok I'll have to ask @Mike Creuzer for some help.

PS: Looks like it's only happening on Firefox. (Using version 37.0.2 and tried 38 beta as well)

Is that UI.Flex or Flexile?

Firefox, minimize browser window a bit to see issue. Sometimes if too many tabs doesn't even need to be minimized.
