Re-walked the glyph path a 4th time; confirmed ammo digits use the same textrelated.c path (gunfire.c:5906 -> textRender -> textRenderGlyph), no separate HUD-number renderer. Same contradiction as M-6/7/8: every stage runtime-verified non-mirrored, glyphs still X-flip. Needs RenderDoc or the asymmetric-texel experiment, not another static trace. New finding: gfx_pc.cpp:1546/1551 D74 wrap-block is dead code (cms & G_TX_WRAP with G_TX_WRAP==0) + OOB vertex-vs-texunit array index. Latent, logged not fixed. New docs/GRAPHICS-BACKLOG.md collects all cosmetic items (D74/D75/D76/ D77/D114/D116) below level-progression + crash priority per user.

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. |
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_f32byte order).
