on 1.21, I have a Velocity network under which there is a Survival server that has Oraxen + MythicHUD ( + MMOcore etc. ). The configuration of the HUD is correct and it usually works perfectly, but sometimes, when you enter the server (the survival one) the HUD is completedy shifted downward. The hotbar overlay goes under the screen and another top left HUD also shifts downward. it's like the offset randomly breaks, and if I go back to the lobby and come back, usually it gets fixed. I guess it's not Oraxen and the resource pack but MHUD not detecting the screen properly sometimes (my assumption). When this problem happens, also center popups are shifted down.
