sorry，my  OS   has   no    problems  as  yours，the   admin   wil  help  you，wait ，     please

I don't have those bad glitches , the only thing so far is that the dock will take a little while to show up ; but yeah i can not update to the Nvidia  drivers ,  it gives a list of files  of  files that their dependencies can not be resolved :

nvidia-driver: Depends: nvidia-driver-libs (= 367.57-1+deepin) but 367.57-1+deepin is to be installed
               Depends: nvidia-driver-bin (= 367.57-1+deepin) but 367.57-1+deepin is to be installed
               Depends: xserver-xorg-video-nvidia (= 367.57-1+deepin) but 367.57-1+deepin is to be installed
               Depends: nvidia-vdpau-driver (= 367.57-1+deepin) but 367.57-1+deepin is to be installed
               Depends: nvidia-alternative (= 367.57-1+deepin) but 367.57-1+deepin is to be installed
               Depends: nvidia-kernel-367.57 but it is a virtual package
the open sources drivers work ok for me and the best part is that all my font problems are gone
Reminder:

The Beta edition has many known problems and imperfect functions. It is not recommended to use it as main system in work environment and daily use.
Please fill the “deepin 15.4 Beta Testing Questionnaire”  to improve our system in 2017/02/27~2017/03/13.

I also tried this method, unfortunately nothing, seems to be a problem Xserver.Xorg.

However, for now I have to remove Deepin, too many young, I return to the most powerful and stable Arch Linux, for now... when you exit the Deepin 15.4 Output Stable, I'll try again.

I've the same problem, but  i don't have any idea how to solve this!

I Desktop is a AMD A8 - Radeon R7

I have the same problem and I am using a R9 270. Anyone got a solution for this?

Hi, I have the same problem, I return to Deepin after trying another distros, so I decided to try the beta, unfortunately I found this glitch, Help please!

I had the same glitch, i fixed it after installing my 750 ti Drivers, so that is the only solution i think.

Hi everyone, I found a solution that worked at least for me:
I've installed deepin with spanish as system language because is my native language, but in this archived thread an user suggest to change the system language to english, so that's what I did an it has worked, I  don't mind using the OS in english so it's fine for me.
Hope it helps and soon they fix this issue.

The graphics glitches have been fixed in 15.4 RC2 (Intel CPU i5 7th generation / Intel integrated GPU).
Please make deepin 15.4 distribution release a little faster when the operating system is virtualized in VirtualBox with Guest Additions installed into deepin.
The Deepin Desktop Environment is still too heavy for the CPU. LXDE and XFCE run faster than DDE.
