How can I await the work completing? Edit My original question assumed the premature continuation was caused by the design of the API, so here's the real question. When awaiting Dispatcher.RunAsync using an asynchronous delegate, using await within the delegate's code, the continuation occurs when the await is encountered, not when the work has completed. How can I await the work completing? Edit 2 One reason you may need to

Should calling setCache actually improve performance i.e. frame rate some or most of the time? I am unable to observe any change in frame rate when I use setCache(true) and I apply scaling and other transforms. 回答1: Do I need to use setCache(true) on a Node for a cache hint set by setCacheHint() to actually have any effect? Yes. The cache property is a hint to the system whether

Does the alignas specifier work with 'new'?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: My question is rather simple; Does the alignas specifier work with 'new'? That is, if a struct is defined to be aligned, will it be aligned when allocated with new? 回答1: If your type's alignment is not over-aligned, then yes, the default new will work. "Over-aligned" means that the alignment you specify in alignas is greater than alignof(std::max_align_t) . The default new will work with non-over-aligned types more or less by accident; the default memory allocator will always allocate memory with an alignment equal to alignof(std::max_align
