Submitted. It seems weird you couldn't reproduce it, though.
Perhaps it's a macOS vs Linux issue?
No, this is not specific to Mac OS or Linux. My guess is that you might be having native d3dx override in your Wine prefix, this could be the reason you don't see this.
Ah, that's right. A lot of older Touhou distributions come with DirectX 9 overrides. I have them up to Touhou 13, which aligns with what has occurred here. I've accepted the bug link for Touhou 11 - it might be worth checking how far back the issue occurs, in case 10, 12, and 13 also exhibit the behavior.
