The `cache.curves_cache.proc_attributes_buf[i]` is independent of the subdivision level. Therefore it's not freed when the subdivision level changes currently. However, the check assumed that when no attribute was changed, the final subdivided buffer is non-zero, which is not true when the subdivision level changed. Now directly check whether the attribute is cached already. Pull Request: https://projects.blender.org/blender/blender/pulls/119216
