Description

[The following is a template to help you fill out a more informative
report]

Note:
Many games do not run yet, or have known problems. Please do not report
those games without giving any more information. That means reports like
"Game XYZ crashes" are not helpful. Instead try to include as much debug
information as possible. Also try to search the issue tracker for similar
bugs before creating a new issue.

--------------------------------------

  1. Game Name and ID (as it appears in right click > properties: "GZ2P01",
    "RSBE01", etc):
    GKYE01

2) What is the expected output? What do you see instead?

In kirby air-ride without fast mipmaps the graphics dont render correctly like in the picture

3) Did the game ever work correctly (i.e. not have this problem) on an
earlier version of dolphin? Please specify the exact revision when the
problem began.

no graphics issue before Fast Mipmaps was Removed

5) What version of dolphin are you using (32bit/64bit along with the
version as it appears in the title bar, etc)? Do not say 'latest version'
this changes multiple times a day.
On what operating system, drivers, and hardware? Be sure to list OS,
graphics driver information, and video card model if you are having
graphics problems, for example.

VER 3.0-689

I get this too, though I assumed it was just my GPU before. Dolphin still automatically generates mipmaps in some situations where it shouldn't, according to a comment in the code - I'm guessing this bug is caused by that.

Just did some quick research, the mipmaps apparently get decoded correctly. Issue doesn't happen with software renderer.

Changing "tex.texMode1[i&3].max_lod >> 4" in the TextureCacheBase::Load calls in VertexManager.cpp to "tex.texMode1[i&3].max_lod >> 5" apparently "fixes" the issue. I doubt that's what we want to do there, however.

I'm seeing mipmapping glitches similar to this in Sonic Adventure 2, as well. (Though, this by itself is probably of little help...)

Please provide a "good" and "bad" screenshot for comparison.
I have no idea what is incorrect in the screenshot of comment #1.
