layers 1. The 3-Layer Wallpaper Composition Pipeline
Telegram's wallpaper rendering engine organizes the chat background canvas into three distinct GPU-composited layers, allowing real-time effects to operate without degrading chat scrolling frame rates.
Layer 1: Base Canvas & Gaussian Shader
Renders the underlying high-resolution photograph or multi-stop mathematical gradient. When 'Blurred' is toggled, a hardware fragment shader applies a Gaussian blur to ensure chat text remains 100% legible.
Layer 2: Algorithmic Vector Pattern
Overlays repeating vector icons, mathematical doodles, or isometric shapes with custom alpha opacity. Vector patterns scale infinitely across ultra-high-DPI phone displays without pixelation.
Layer 3: Gyroscope Parallax Motion
When 'Motion' is enabled, device accelerometer and gyroscope events translate the background plane inversely relative to the message bubble plane, creating a physical perception of depth.
Universal Cloud URL Architecture
Every created wallpaper compiles into a cryptographic cloud identifier accessible via https://t.me/bg/..., allowing friends to apply identical color grades and patterns in a single tap.
smartphone 2. Platform Navigation Pathways: Android vs iOS
Android Pathway (Chat Settings)
Open the drawer (≡) > Settings > 'Chat Settings', tap 'Change Chat Wallpaper'. Choose a gallery photo, color gradient, or online search result.
iOS Pathway (Appearance Settings)
Go to Settings tab > 'Appearance' > 'Chat Wallpaper'. Pick an existing theme or tap 'Choose from Photos' to select custom imagery.
Configure Blur & Motion Effects
In the preview screen, tap 'Blurred' to soften the image, or 'Motion' to enable gyroscope parallax tilt tracking.
Share or Set Globally
Tap 'Set Wallpaper' to apply locally, or tap the Share icon to generate a t.me/bg/... link to share with your friends or channel subscribers.
