Flashing after the Railroute is started

I'm playing Rail Route on MacBook Air m1 with macOS 15.5, and the game just start flashing after I launch the game. I have already installed this game twice and this problem still occurs. Anyone knows how to deal with this problem?

Solved, the problem only occurs using the beta version of the Steam client, I put the stable version back and now the game starts correctly with both the stable version and the next_unity

I’m experiencing the exact same issue with the MacBook Air M2 running macOS 15.5. I’ve also tried uninstalling and reinstalling. I even tried switching to a beta version, but the result is the same as in the screenshot.

Same problem on m2 pro

It seems to be some incompatibility between Unity version (October 2024) and macOS 15.5 (May 2025). I am now installing the recent unity version & will make a build using it. I will keep you informed.

Please switch to next_unity branch via Betas in Steam Client - it contains the Unity 2021.3.45f1 build (last 2021 LTS version available).

Let me know if it helps.

If not, we will try Unity 2022.3.62f1 build but there is a higher risk of unexpected problems between two major versions.

At least on my part same problem with next_unity branch

2022.3.62f1 build is on the way

Mišo [developer] 28 Jun @ 2:07pm

2.3.21.2 (Build ID 19038999) uploaded to next_unity branch. You may have to restart Steam Client to fetch the new version.

We are aware that the checkboxes do not work - more precisely, they do not show their state (but clicking toggles it invisibly). If the update solves the problem, we will fix these minor issues subsequently.

The problem persists, now the screen with the glitches is always the same while before it changed continuously
