Cursor Showing up in opengl game

I’ve made a snap package for an open-source project called re3:
https://github.com/0x0000ff/re3.git

There’s a mouse pointer in the middle of the screen in the game and menu. Any help in removing the cursor would be appreciated.

Thanks.

It’s probably worth mentioning that I’m using Debain 10 with a kernel from backports- my bad. I’ve also got some details of my hardware:

I’ve Tux Kart installed as a snap, and that doesn’t exhibit the same problem.

Does the cursor show up in the non-snapped version?
