The change addresses the handling of flip operations to reduce flickering during rendering.
Rendering improvements:
packages/core/src/RenderingEngine/Viewport.ts
: Added a check forflipHorizontal
orflipVertical
to ensure the view presentation requires a flip, which triggers another re-render to take effect. This aims to reduce flickering by waiting for the camera and flip operations to complete together before rendering.
