Performance Issue with Challenges screen - Game fully freezes for 500-1000ms

I've noticed this issue for a while now and it's annoying me enough to finally report it. It stands out because no other screen/tab/window anywhere in the client does this, it's only opening the Challenges screen.

The closest I've seen before was when, for a certain time, the passive tree had some noticeable delay when opening, but that's no longer really the case, or less so.

My suspicion is that because the information is not preloaded it loads a tremendous amount of information in real time - all Achievements, Challenges, and Bestiary.

The more action there is on screen, the worse the stutter, up to a second sometimes, which is jarring and dangerous.
