UI elements keep repositioning themselves on their own

[Mhaeric]

I have the problem with self-moving vertical hotbars too

I have noticed, that when I open the character config menu, make changes in the checkboxes (pop-up text) and then push the CANCEL button (apply exit without changes), my hotbars moves. That is some kind of a trigger of this bug

Actually, that is very likely exactly what triggers it for me too. In all cases but the first where I noticed it upon logging in for the first time today, shortly before it happening I had adjusted the pop-up text and flying text settings to test them. I can't recall if I had done something similar or not prior to logging out yesterday or not, so I'm not sure about that one case.

Edit: just confirmed this is exactly the cause, although any changes made trigger it not just the pop-up text setting. Watched it happen right as I clicked OK on the confirmation to exit without applying changes.

Here are the steps to duplicate this 100% of the time:
Step 1: open Character Configuration menu
Step 2: make a change anywhere but do not apply (changes confirmed to cause the bug include toggling checkboxes for pop-up text or display inventory grid)
Step 3: click on close (without clicking on apply)
Step 4: click on yes in the confirmation window
At this point you will see the vertical hotbars change position.

(P.S. Here's a tip to make this a bit less of a hassle for those it happens to: Save your layout to two different slots so you have a backup, and when it happens click on the cog in the hud layout menu and copy the backup to the slot you use as your main layout. E.g. I save mine in both layout slot 1 and 2 and usually use slot 1. When this happens I just copy slot 2 to slot 1 instead of moving them all back manually.)
