Hey again, guys and gals. I found another annoyance I haven't spotted before... Look at this screenshot, and the area covered by the "Opponent Vitals" UI element. Basically, it's way too large and the area covers the quickslots bars at the bottom of my screen as well.
The problem: Opponent Vitals element seems to get some kind of "always on top" setting on it occasionally. Sometimes when I have a target selected, it blocks me from clicking the first five quickslots on the first quickslot bar; the default, unmovable bar that is. Second and third bar in the screenshot are undocked, and the skills in those two are clickable.
6th skill in the first bar is only half-covered by the Opponent Vitals element. When the issue hits me, left half of that icon is not clickable (it doesn't show the skill tooltip for example), right half of it works. I haven't spotted this issue before, but as we're talking about bugs, I think this does classify as one.
I can't see any reason for that element to be so large anyway, as less than half of the reserved area is ever being used. Could the area used by this UI element be reduced in size - not just to avoid this kind of issues, but also to allow for more accurate customization of UIs? In that screenshot, vitals are already pretty much as low as you can put them. I'd prefer having them even further down on the screen.
As can be seen in the screenshot, I am indeed using Custom UI. However, I also tested it with the default UI and the problem appeared with that as well; Opponent Vitals are sometimes blocking the access to docked quickslot bars... In fact, with the default UI, all three quickslot bars became blocked instead of just the first one.
The issue may be related to alt-tabbing between a full-screen game client and desktop / other softwares. I don't see why alt-tab should break it really, but it seems to be nearly foolproof method for "getting this bug to work", if such expression can be used. :P
Edit: Ok, the post below this says it's been there at least from 2010. I've never spotted it, though I rarely click the icons on the FIRST quickslot bar. Paying a little more attention showed to me that it's in fact blocking bars 1-2 with the Custom UI, bars 1-3 with the Default UI.
First bar is always blocked after alt-tabbing or selecting a new target in both UIs. Second bar is blocked in both UIs, until any skill (or an empty skill slot) on that bar is clicked. Third bar has not been blocked, not even one single time, with the Custom UI, but when using the Default UI, it works similarly with bar 2; skills behind the vitals are unclickable until you click one that's available or use one on that bar through key mappings.
Annoying. If the element area had it's pointless bottom half removed, there would be no issues with the current positioning of that element. What surprises me though, is that
player's own vitals do not block anything, ever. Not in my game client at least. That feels strange, as the elements itself seem like they were simply copies of each other, just with the portrait mirrored.
