The Mana globe stays blue when my character transforms into Wearbear or Spriggan Form. It should be orange as far as I know. It never worked for me (but I guess for everyone else).
I’m running on Linux with an AMD graphics card and the open source drivers (as is typical with AMD).
Edit: This is (kind of) fixed. But sometimes, I see weird stripes across the Rage globe. But since nobody else seemed to have this issue, I guess that it is on my end only.
