cannot maximize window

[赵磊]

I set auto hide Launcher,but when I do this,I cannot maximize window:the window cannot cover the launcher area
my english is not very well,if you can understand Chinese ,pls read the follow Chinese words:
我设置了启动器自动隐藏,而且启动器也自动隐藏了,但是最大化窗口的时候发现当前窗口并不能完全最大化:最大化的窗口不会覆盖启动器区域

Google translates as:
I set the launcher to automatically hide, and the launcher is also automatically hidden, but when I maximize the window, I find that the current window cannot be fully maximized: the maximized window will not cover the launcher area

I can't reproduce this. Try on fresh live usb. It seems like a xorg bug. Can you give some screenshot ? Press Alt+F2 and try running `compiz --replace` and see if that fixes the issue.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 14.04 (trusty) reached end-of-standard-support on April 25, 2019

Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
