[图片] [图片] 开放数据域里设置分享图片，分享功能一切正常，但分享时还是截图

wx.shareMessageToFriend 开放数据域分享图使用 imageUrl、imageUrlId 自定义转发图片配置已经通过审核，但分享时却是游戏截图。是因为开放数据域不支持远程图片吗？这种配置好的也不支持吗？

著作权自我声明、代备案授权书 被驳回，“本工作室”一词被标为有问题，但未给出正确用词。 按照范例这里应填写 “我司” 或 “本人”，工作室的话，这里应该填写什么呢？ 在线等，急。。。 [图片]

场景：俺在做的微信小游戏【首帧使用webgl渲染一张背景图】优化启动速度，子包的游戏包加载完成后自动运行【游戏场景】 问题：下面的渲染代码 1.【普通模式】iOSHighPerformance:false - webgl渲染bg.png【正常】 - 子包加载完成后【游戏场景渲染正常】 2.【高性能模式】iOSHighPerformance:true - webgl渲染bg.png【黑屏】 - 子包加载完成后【游戏场景渲染正常】 - 无相关报错日志 PS：高性能模式 - 无报错日志，俺对webgl不太懂，希望有人帮俺看看，谢谢啦 渲染代码： // vertex shader let VERTEX_SHADER_SOURCE =` attribute vec4 a_Position;
