EDIT: Fixed the issue!
I downloaded Touhou 11: Subterranean Animism from Lutris site, and it worked in fullscreen
I noticed that it uses lutris-fshack-7.1 wine version, so I applied it to my Touhou 14: Double Dealing Character configuration and it works! 
I’ll leave this post for people who have the same issue
Hello!
I tried to play Touhou 14 in full-screen, but I can only see black screen. Music plays and I can click on different options, even play the game (without seeing anything)
I had the same problem in Touhou 12, so I think it applies to all Windows Touhou games (Touhou 6 - Touhou 18)
OS: Gentoo/Linux x86_64
WM: i3 (I had the same problem on MATE de)
CPU: AMD Ryzen 5 4600H with Radeon Graphics
GPU: AMD ATI 05:00.0 Renoir
GPU: NVIDIA GeForce GTX 1650 Ti Mobile
First time reporting an error, and I didn’t know how to upload json file from lutris --submit-issue 
Also, I noticed that I picked staging version of wine here… The same problem was on stable version
