Too much faster curse activation removes the curse ground visual effect

Hello, I noticed after adding my last jewel and reaching a good amount of "Fast curse activation" that the ground effect of the Despair or Enfeeble curse no longer displays at all.

The effect is still applied on enemies, there is just no visual indication of the curse radius on the ground.

When removing the jewel, it is displaying correctly, and it disappears again when adding the jewel.

I'm not sure I can find the exact amount of "Fast curse activation" I have from the panel. I have 35% from jewels, 70% from passive skill tree.

Looks like reaching the 100% faster activation curse does it.

Thanks a lot for your amazing work!

Thanks for posting this, thought I was going crazy. I have all my curse passives on weapon II but when I switch to a Staff for casting curses it would perform the cast animation but no AOE on the ground.
I saw this post and realized that it started happening after I added a couple better jewels.

Thanks man, would have never guessed that it's related to the activation time. What makes me wonder however is why this only happens to one of my curses?! Running flammability and vulnerability on my necro and vulnerability does show the radius as expected.
[Edit] nvm, applied Focused Curse to it -> removing it shows the curse radius
