DPI/UI scaling is making the context menus (when you right click on an npc) show up near the edge of the screen and not at the mouse cursor. It will even change the location based on where on the npc you right click. Meaning, don't click their feet or the menu won't show up on the screen.
I'm using the new UI scaling at 175%. When I switch it back to 100% the right click context menu shows up correctly. This wouldn't be so bad if I didn't have to right click some mobs to get quest item updates (I'm looking at you steamfont tradeskill spider). I should point out, right clicking the hotbars works perfectly. It's just npcs/mobs.
Is this still happening for you? I've tried reproducing this at 4K in all the combos of windowed/fullscreen, all the scale values, and with the software cursor on/off and things are appearing where they should be
A similar thing happened with the occasional name of an item showing way off to the right on the bottom of the screen. This happened when I tried (in 200% UI scaling on my 4k monitor) to click on the bottle at the shoreline in Queen's Colony, so I could leave my character's name on it.
But most of the time I tried clicking on it, nothing would happen at all. Then a couple of times, the bottle name blinked on and off quickly then disappeared, showing way off to the right at the very bottom edge of my screen. I play Windowed, not full screen, if that has something to do with it.
I was able to repro this issue, a ticket is in
I am running 200% UI on my 4k monitor, and I just got a treasure chest from a boss, and it opens when I click on it, but nothing pops out for loot. Then it says "You are too busy to loot right now" if I keep clicking on the chest. I tried relogging but nothing changed. This has happened twice now. I also tried hitting F10 but it doesn't focus on the chest at all, so nothing changes.
I know this boss drops loot every single time, and the chest is there, so since when do we get a chest without loot in it? Since never, until today, lol. And this boss doesn't drop lore items, and I'm not boxing, I'm just using 1 account and not teamed.
I think it's related to OP's original post problem, but I'm not a dev.

I wonder if my bugged clicking of books and turning pages of them and starting quests is linked to this?
I dont seem to be having any issues on my end interacting with books, not sure if this is a related issue but if you can give me more context to test with I can try to look into it again
Thanks everyone for your reports!
