So you're saying that it doesn't happen when the tweaker is not running. But the issue happens if the tweaker is running, even when all of the options are off. Is that right?

That's not something anyone ever reported about before. The only thing I have in mind we can try is the following: I can create different versions of the tweaker with some of the functionality removed, so that we can track which part of the functionality causes the problem. Are you willing to try different versions of the tweaker?
