GRAPHICS-BACKLOG — known cosmetic / rendering issues

Deferred below level-progression and crash work (user priority, M-11). Minor graphical glitches are acceptable in the current state. Fix these once the game is playable start-to-finish without crashes.

Open

ID	Symptom	Status / notes
D114/D116	HUD text + ammo digits render each glyph individually X-mirrored (screen positions correct, texture content flipped). Likely also explains "inverted" guard skins / mislocated door props.	Root cause NOT found after 4 sessions (M-6/7/8/11). Every stage textRenderGlyph→GBI→fast3d→buf_vbo→GL runtime-verified non-mirrored (GE_D116 [D116/vbo] probe). Contradiction unresolved. Next attempt requires a RenderDoc/apitrace capture of one glyph texrect, or the asymmetric-1-texel-texture experiment — do NOT re-run the static trace, and do NOT apply a global texrect S-swap (mirrors the whole screen).
D74 wrap-block	gfx_pc.cpp:1546/1551 PORT block is dead code: guard cms & G_TX_WRAP with G_TX_WRAP==0 is always false; and it indexes per-texunit [2] arrays with the vertex index i (0..2) → OOB if reached.	Latent. Harmless for CLAMP glyphs; could affect wrapped textures on triangles (room panels, model skins). Fix: cms == G_TX_WRAP, and compute the tile window once per tile not per vertex. Verify against tools_pc/golden/ after.
D75	Nintendo logo mispositioned; gun-barrel Bond model absent; cast-roll character models absent. (Rareware logo OK.)	Front-end 3D model path. Partially overlaps D114 (shared mirror on asymmetric content). Triage plan in PCPortResearch.md §F D75.
D76	2D disclaimer screen only partially drawn.	§F D76.
D77	No audible music on PC.	Phase 3 (audio). §F D77.
D116 (HUD)	(subset of D114) proportional-font strings + ammo counter mirrored.	Same root cause as D114.
D148	Level-end cinematics don't play. Dam: hitting the exit trigger should show Bond rappelling down the dam (the bungee jump); instead it cuts straight to the mission-complete report.	Scripted cutscene / cinematic-camera + Bond rappel anim. Likely D75-family (front-end / cutscene 3D model + anim path). Found M-27 during the first full Dam→Facility playthrough. Progression is unaffected — the report and next briefing load fine.
D149	Front-end MISSION COMPLETE / mode-select 3D models (dossier, wallets) render as garbled full-screen geometry or not at all — one of the compiled sub-DLs (seg5+0x9ee4) is malformed, D146 now skips it instead of aborting.	D75 family. §F D146.

Resolved (for reference)

• D70–D74: intro-logo pixels (Rareware logo renders correctly).
• D103: viewport / native-resolution half-frame.
• D105: room geometry Z-buffer never cleared (G_CLEAR_DEPTH_EXT).
• D106: sky-void through doorways (portal near-plane min>max).
• D107: blurry ceilings/wall-panels (LOD mip tile fabrication).
• D112: skeletal models were "3D lines" (d43_emit.py put_f32 byte order).
