终于，国际友人都受不了了。。。。。
Finally, the international friends can not stand it...

重启，在设置里面开关grub主题或许有用。
Restart and turn off&on grub themes in Settings may work...

It was the first thing I did, but fonts are still ugly and menu is oversized. (Something about 1200x700)
I will try to change theme.txt by myself, but I don't understand why deepin team has disfigured it.

因为我们觉得前面的版本的也很丑，所以大家要求他们必须改改改，立马改，没想到他们没改好就发出来了。
Because we think that the previous version is ugly too, so we asked them to change, immediately change, Unexpect that  they did not improve too much on the issue.& Be anxious to show it to us。

不要着急，他们会把grub改好看的，给他们点时间
Don't worry. They'll make grub look good and give them some time.

I have fixed grub by myself:
I have recreated grub fonts using grub-mkfont, then fixed a theme.txt file.
For me the problem was in the fact, that developers just missed and grub used some standard, antialiased ugly fonts.

And menu itself is a bit oversized. I know, I can fixe it by myself with editing theme.txt file and all deepin grub theme, but I don't want to waste much time googling manuals

Just in case somebody doesn't know, you can change the grub image by dragging any image into the boot loader on Control Center > System Information > Boot Menu

I just disabled the theme in the control panel until further notice. I liked the old blue theme much better.
