This update applies only to the macOS and Linux versions.
On these platforms, the game uses SDL2 to render a 640×400 texture to the screen at 60 FPS. We discovered that the texture buffer (framebuffer) was incorrectly allocated for only 399 rows (640×399), and have fixed the issue.
This bug could cause crashes and other problems. We believe this update resolves them, but since we do not have access to hardware on which the issue can be reproduced, we cannot guarantee that the fix is complete.
If you encounter any further issues, we would greatly appreciate it if you could report them on the Community forum.
