Reported: menu / room textures look 'interlaced' (alternating garbage rows). Root cause (docs/TEXTURE-GLITCH-ANALYSIS.md RC2): GE's texGetDepthAndSize() packs base level + every LOD mip into one gDPLoadBlock, so fast3d's upload height (size_bytes / row) runs ~1.3x taller than the base image and the mip bytes render as rows below it. GE_DTEX=1 confirmed it: 64x64 I4 uploaded 64x87, 65x65 -> 65x95, etc. Fix in import_texture(): when LOD is active (rdp.tex_lod) and the load is a plain full-width block (not a windowed gfx_dp_load_tile - the D74 sub-tile / Rare-logo case, which is lod=0), clip size_bytes to the SETTILESIZE base-tile height. GL then builds correct mips from a correct base. New knob Video.FixMipTextures (default 1; =0 restores old upload, verified byte-identical to golden -level_09 3/3). BUNKER1 with the fix on: side-wall textures visibly cleaner, geometry/HUD unchanged; Silo unregressed. -level_09/-level_20 framediff WILL flag with the fix on (textures changed for the better) - refresh golden after the user confirms the menu + Depot look right. New GE_DTEX=1 env probe logs load params for the first 64 textures.
