As the title says, the GIANT window that pops up when an objective is complete fills the screen. This is annoying, and actually killed me before I realized it could cover enemies. Please make the enormous text/loot boxes more transparent. Better yet, make a modest sized icon that doesn't block nearly half of the screen, obscuring enemies. As it is, the best work around seems to be running all over the map to reveal the monsters that remain so you can target them, as you can't even click on the objective rewards area because instead of targeting the mobs hiding under the rewards, it targets the rewards.
