border in Virtual Desktop

I tried to install a music player (Netease Cloudmusic) on Deepin 15.9 with Wine
4.4
Normally, this application's borders is drop shadows, but now, there is a thick
border line around the window.

What's worse, after I disabled Virtual Desktop, this border show in the wrong
place.

How could I fix it?
