	//   ② vkDeviceWaitIdle 等待所有"已 submit 但未完成"的 cmdbuf 跑完，确保
	//      销毁旧 image/view 时 GPU 已经不再采样它。
	//   ③ destroy → create → updateTexture → refresh_descriptor_set_bg
	//      全部在锁内完成，期间 m_descriptor_set_bg 处于"指向无效 view"的中间
	//      状态，但因为渲染线程被锁阻塞，这个中间状态对 GPU 不可见。
	// 注意不能调 base::processWithVulkan，那会再次 lock createTextureMtx 死锁；
	// 直接调 createTexture + updateTexture，这两个 base 方法不持 createTextureMtx。
