The apitraces from when using i965 and llvmpipe

The textures in the game Cat Girl Without Salad, which runs though Wine are
significantly aliased when using hardware rendering. In the terminal the
following message constantly appears:

0032:fixme:d3d:texture2d_blt_fbo Unsupported filter mode
WINED3D_TEXF_ANISOTROPIC (0x3).

When setting LIBGL_ALWAYS_SOFTWARE=1 llvmpipe is used and the textures appear
correctly, as they are when playing the game on Windows. The following two
images show the difference at the main menu:

i965: https://i.imgur.com/K02TJ0v.png

llvmpipe: https://i.imgur.com/lk8rpMn.png

The attached file has the apitrace from both i965 and llvmpipe compressed. The
apitrace from i965 is pretty strange, it did not replay correctly here, opening
four windows and showing only a black screen.
