Any chance that you unlocked hero points through World vs World using the Heroics Notary. Heroics Notary - Guild Wars 2 Wiki (GW2W)

I contacted support as well at first and was told to go in game and do a bug report or go post on the forums. 🤔 Guild Wars support has been awful in my last few tickets. Not sure why I even tried to put this in as a ticket figuring they would not be helpful. Their support used to be good.

I am having the same issue. I have all paths completed of all the dungeons and completed Hobby Dungeon Explorer 50 times and now I cannot purchase any gifts for the legendries. I created my account during the early preview days of Guild Wars2.

I did not have time to read through the entire guide that you used, but have you tried turning on Vertical Sync (VSYNC) in the game? I was having this problem and it was terrible. It was after I just moved to a new computer and monitor and did all kinds of testing including going back to my old setup. Then I started noticing it there as well. The new monitor has a higher refresh rate so that is why it seemed much worse. Enabling VSYNC has greatly reduced it for me, but it still happens at times but does not seem as bad. I realized later it all started with DX11.
