docs(session-replay): Clarify iOS performance impact on older devices#16205
Conversation
Overhaul the Session Replay performance overhead documentation to better communicate the potential for scrolling stutter and frame drops on older iOS devices. This addresses feedback that the documentation didn't clearly explain the impact on scroll behavior. Changes: - Add dedicated "Performance on Older Devices" section with clear warning - Explain why stutter occurs (main thread blocking during screenshot capture) - Document scenarios that increase likelihood of stutter (heavy animations, complex view hierarchies) - Add "Understanding Main Thread Impact" section with timing details - Include View Renderer V2 performance comparison table - Add cross-references from React Native and mobile docs to iOS-specific guidance Closes getsentry/sentry-cocoa#7225
