Created attachment 112164 [details] the problem which is. when I copy the words that from web pages and paste them to Writer,where appear many grey blocks between the words.My current LibreOffice version is 4.3.5.2. I'm using Chinese simplified. Steps to reproduce: 1. copy the words from web pages,for example:"http://blog.csdn.net/bxd1314/article/details/40779405",I copied the words from it and the problem occurred. 2. past it to Writer.
try unflagging some of the options under the "view" menu there's one that should toggle those grey blocks on/off I have LibO with Italian UI so I don't know exactly how's is called in your language. tell me if this fixes things
