What's the problem? Describe what went wrong.

F-zero GX uses a similar effect to Mario Sunshine in stages with water. Attached are some renderdoc captures of textures and their mipmaps, showing that the mipmaps do indeed contain different textures. Despite this, arbitrary mipmap detection does not seem to trigger on them.

What steps will reproduce the problem?

Play F-zero GX, and go to Big Blue: Ordeal, the last track of Emerald Cup. Alternatively, use this savestate for 5.0-16607, which is for the japanese version of the game, with a debug menu. This will load you into the stage in the debug stage viewer, so you can freely move the camera. https://cdn.discordapp.com/attachments/390278971880636428/982778464501383228/GFZJ01.s01 . Then, simply turn on arbitrary mipmap detection, then change the anisotropic filtering option in dolphin and watch as the depth of the specular mipmaps change.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
5.0-16607

Is the issue present in the latest stable version?

[Yes/No and version number here]

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[First broken version number here (if applicable)]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

configuration files, savefiles, savestates)
