Software rendering doesn't support hardware bitmaps

[chachako]

一个比较奇怪的 Bug，第一次 push "BlurScene" 时从这个 Scene 的 onViewCreated 中执行 activity.window.decorView.draw(canvas) 没有出现任何问题，但当我 pop 掉这个 "BlurScene" 再重新 push 后就崩溃了

有详细点的崩溃栈吗

进入页面后，后续是不是从glide啥的加载了 hardware 的 Bitmap 到 ImageView 上，这种 Bitmap 没法绘制到手动创建的 Canvas 上吧

没有...就单单的截图一下activity到画布上

能查到这个 ImageView 的 Bitmap 哪里来的吗

感谢，排查完了，确实是 ImageView 的问题，但是是 ParentScene 的，我将上一个 Scene 中列表的所有从 Glide 加载的图片取消掉就不会发生这个错误了。

但是奇怪的是为什么第一次 draw Canvas 不存在问题而从第二次开始就会崩溃呢？

这就不晓得了
