[Bug] WebGL / screenshot-basic game-view capture produces horizontal striped images on Enhanced (no DLSS)

[YG0007]

Summary

Capturing the game framebuffer via the standard WebGL / CfxTexture game-view path (used by screenshot-basic, screencapture, and in-resource NUI capture) consistently produces images with horizontal scanline/stripe corruption on GTA V Enhanced. This happens with Frame Generation / Frame Scaling off and with no DLSS (GTX 1660 SUPER). Upload to a remote host succeeds; the saved image content is already striped. Legacy-style capture is expected to return a clean game frame.

Steps to Reproduce

1. Join any Enhanced server with screenshot-basic started (stock citizenfx resource is enough).
2. Graphics: Windowed Borderless, Frame Scaling = Off, Frame Generator = Off, Anti-Aliasing = TAA (no DLSS available on GTX 1660 SUPER).
3. From a client script (or phone/camera resource), activate cellphone camera optionally:

• CreateMobilePhone(1)
• CellCamActivate(true, true)

4. Call:

exports['screenshot-basic']:requestScreenshotUpload('https://api.fivemanage.com/api/v3/file', 'file', {
  headers = { Authorization = 'YOUR_TOKEN' },
  encoding = 'jpg',
}, function(data)
  print(data)
end)

5. Also reproduce without CellCam: use only a DEFAULT_SCRIPTED_CAMERA + RenderScriptCams(true, …) then the same requestScreenshotUpload.
6. Open the returned image URL.

Same corruption occurs when capturing from an in-resource NUI WebGL context using the CfxTexture “magic” TEXTURE_WRAP_T hook (same backing path as screenshot-basic / screencapture gameview).

Expected Behavior

The capture contains only the clean 3D game render (as on Legacy), suitable for phone cameras / galleries / uploads.

Actual Behavior

The image is corrupted with horizontal stripes / scanlines (often dark with thin colored lines). HTTP upload still returns 200 and a valid CDN URL — the framebuffer sample itself is bad.

Related: #156 (composited/NUI frame with DLSS). This report is without DLSS / FG, so may be a separate or broader game-view capture regression on Enhanced.
