Did you try to disable hardware acceleration in the Aurora settings?
Didn't think to check for that, but have done some more testing now.
It seems that turning that off has resolved the issue.
While testing I did run into an issue with the trainer failing to activate.
I have so far only used it with Tiny Tina's Wonderlands on Steam
Debug screen showed this message:

are you using the 1.3.4 version of Aurora?
Yes I am.
I did post that in my OP, second line.
