I think you’re on to something w/ transition scale or animation scale, even though I’m not seeing them in GrapheneOS settings even after activating developer mode. I may just need to request this feature in GrapheneOS or look for a third party app that unlocks this setting. You’ve also given me a new phrase to search for, so thank you for that.
EDIT: I found Transition Scale and Animation Scale in GrapheneOS after activating developer mode, not sure what I did differently this time. Alas, neither of those settings solves the problem, so the hunt continues.
That’s some solid form, 10/10. 🏅
