Start by reproducing the linked Papa Louie 2 page on the reported Android Mali-G57 device and review the stack around ruffle_render_wgpu::backend::WgpuRenderBackend::resolve_sync_handle and copy_texture_to_buffer. Done means the page no longer panics when BitmapData/copyPixels runs on a 4096-pixel-limit renderer.
