Fixes minimization crash because of cluster updates. (bevyengine#3369)

# Objective Fixes: bevyengine#3368 Issue was caused by screen size being: `(0, 0)`. ## Solution Don't update clusters if the screen size is zero. A better solution might be to not render when minimized, but this works in the meantime. Co-authored-by: John <[email protected]>
