I start emacs server with systemd. I use emacsclient for several days. 
It doesn't work reliably.

There are 3 problems until now.


1. font-lock works abnormally.

Colors are right after a file being opened. But new text I inserted into 
the buffer are not font-locked.

If I turn off font-lock-mode and then turn on it, the colors become right.


2. company-mode works abnormally.

After I select a completion item, It inserts messy text into buffer.


3. theme loading problem.

In my emacs configuration, It loads a color theme after startup. But the 
colors are not all right. Some colors (background color) are not right. 
I have to load the same theme again in emacsclient and the colors become 
right.

I have add an env of "TERM=xterm-256" to emacs.service.


------

OS: GNU/Linux (centos 7 x86_64)

Emacs: 26.3 nox


I used to use emacs(no server) with the same configurations everyday for 
many years, and have never meet these problem. Is there any limit for 
emacsclient or C/S mode?
