小游戏ID: wx14f777b879e582c4， 已发布体验版。 测试那边多种机型都测试出游戏黑屏问题，微信的版本都是最新的7.0.8，黑屏位置都出现在游戏的3D部分。 只有游戏时间较长时才会出现黑屏，大概二十分钟左右，出现黑屏时没发现报错。 上面MI 9的机型黑屏的概率最高。几乎每次进入游戏玩个十几分钟就会黑屏。 用这款MI9测试发布到QQ平台的体验版也有黑屏现象，但是黑屏概率极低，微信平台要高得多。之前已发布到百度，头条的版本未出现黑屏问题。

在微信后台看到上报了这个错误，微信客户端版本是v6.7.3，错误日志： argument count does not match function definition(beginPath);at requestAnimationFrame callback function 请问这个错误是什么原因？我猜测是低版本针对部分API不兼容，那该如何解决，并且这个错误会影响用户的游戏进程吗？

调试库 ：2.9.1 开发者工具： 当前最新版本（1.02.1911042） cocos creator：2.1.2 小游戏在不校验域名的情况下， 在开发者工具和真机调试都可以正常运行，用安卓机预览就一直卡在100%进不去，点击右上角的三个点点也没有反应，苹果的就可以 ，这是为什么？ 是需要配置好域名吗？

如题，cocos creator导出的单机小游戏，上传体验版后，ios手机可以正常运行，anroid手机加载到100%后无法运行

[图片] [图片] [图片] 在开发工具上是可以正常加载显示这张图的，但是在真机上就不行。我的是小米8

在开发者工具上显示正常，但在手机上预览和真机调试都一直卡在100%进不去是什么原因呢，没看到哪里报错啊

[视频] 当用户点击小游戏icon，并等待1-2s后再次点击icon。之后弹出加载界面，加载到100%后，停留在白屏，无法进入游戏。
