The goal of this project is to demonstrate performance issues related to Compose grid.

To achieve best possible performance examples are kept as simple as possible, also:

• verified in R8 release mode
• contains baseline profile for scrolling
• stable Compose parameters used
• unique and stable item keys applied for grid items

Currently these examples are implemented:

• network images grid with Coil AsyncImage loading
• paginated network images grid with Coil AsyncImage loading
• network images grid with Glide AsyncImage loading
• boxes with random colors grid
• paginated boxes with random colors grid
• modularized (2 static horizontal lists + paginated vertical list) boxes with random colors grid

Simple grid which instantly demonstrates that jank appears while scrolling the grid. Noticeable both by human eye and in profiler:

Same issues as with simple image grid without pagination:

No noticeable performance issues though few janky frames are visible in profiler:

No performance issues visible even without a baseline profile.

No noticeable performance issues though janky frames are visible in profiler:

Same janky frames as with regular paginated grid.
