Issues unresolved

(Linux) Crash when using antialiasing

Some AMD cards and drivers (particularly, in our experience, the proprietary drivers) crash when using antialiasing in Unity.

  • If you experience this, try to run the game with -screen-quality noaa

(Linux) Issues when switching resolutions

  • Some users may have issues with switching resolutions. Developer reports it may be a Unity-wide issue.[citation needed]

(Linux) Volumetric lighting is bugged

  • Volumetric lighting is bugged on most cards/drivers. It's turned off by default in the Linux version but you can still try it from the Video menu if you like. You're likely to get white flashes and/or strange black triangles appearing. Developer is looking into solving this.

Sounds stops playing when transitioning to the next level

When transitioning to the next level, often sounds stops playing. May be related to windowed mode.
