This issue happens with large tree's, a square showing up removing the shadow. This issue existed since at least CE5.2.

Reproduce: Blank project -> Basic Level (just a name, basic settings) -> Import large tree -> Make sure shadows are visible -> Move around it should show up.
I reproduced it in 5.6.1, 5.6, 5.5 and 5.2 (all the engines i had)

This is a nice little feature that I like on Reddit. Would it work okay through federation?

1. path('praise/', views.prise_or_criticize), path('criticize/', views.prise_or_criticize),
这里面的方法名和方法 def praise_or_criticize(request):没对应上
赞应该是praise
2.urlpatterns = [ # 此处省略上面的代码 path('teachers_data/', views.export_teachers_excel), # 此处省略下面的代码 ]
这里export_teachers_excel 应该是get_teachers_data
然后缺一个展示图表的路由

Description

Using the fetch API from WHATWG in Google Chrome, an image upload does not have Content-Type multipart/form-data. Instead, the content type is set to the MIME type (ex: image/jpeg) with a boundary parameter. Setting Content-Type explicitly to multipart/form-data should result in an error (and it does).

运维人员经常将控制台关掉导致数据同步失效，试着用nssm部署成windows服务，发现起不来，看了一下bat感觉是设置的变量在起作用，是不是类里面有使用.bat设置的变量，直接启动java启动会报错

我的一个定时任务为通过 http 方式（使用 OKHttp 发送 http 请求）执行某个方法（例如：http://ip:port/myapp/synFundData）。

当调用上述接口时如果服务器返回504（后台执行时间太长导致超时），请问该定时任务是否会自动重试？因为我从 Nginx 的日志中发现：每隔30秒Nginx 会收到一个同样的http请求，且返回的状态码都是 504，日志如下：

...remote_user=- [16/Nov/2017:08:40:01 +0800] request="GET /xxx/synFundData HTTP/1.1" status=504
...remote_user=- [16/Nov/2017:08:40:31 +0800] request="GET /xxx/synFun
