AI-generatedHigh CPU usage when reusing Cairo image surfaces via create_similar in low‑traffic workloads
Goal: Determine if reusing a single Cairo image surface created with cairo_surface_create_similar reduces allocation overhead for workloads that draw infrequently. Constraints: The reused surface must be updated via direct pixel access or drawing calls, then marked dirty with cairo_surface_mark_dirty before each frame; cairo_surface_finish is required before
