I saw this article and wondering if the GrapheneOS team is aware of this. I noticed also some people report issues like it's stated in the article and wonder if those issues are related to what the article is reporting.

Pixel performance issues reported
https://issuetracker.google.com/issues/337099051
This issue (or duplicates) is in the tracker from Android 14 or even earlier. This issue affects at least Pixel 8 and 9 series from my experience. People say it's all Tensor Pixels though I can't verify that.
I hope Graphene team will address that issue after these articles because Google clearly don't care.
