Dear Author Team,

I am a player from mainland China, and I am honored to have the opportunity to correspond with you. I have found that your game offers a wealth of features, particularly since the 1.14 version, which has allowed me to simulate the railway network I need to showcase with remarkable fidelity. However, there are a few issues that I would like to bring to your attention and discuss.

Primarily, since the 1.14 update, I have occasionally encountered flashing black screens while playing the game (with no display or mouse icon during these instances). This issue seems to arise most frequently when dragging the map, but it also occurs when the game is in a static state.

I have consulted with several other players, and they have suggested that the flashing screens might be triggered when there are numerous train icons on the screen. Currently, players can only hide all train icons as a workaround. However, I believe it would be more beneficial if we could hide them based on categories or "tags." If possible, I kindly request that you consider adding this functionality.

Thank you for your attention to these matters.

Sincerely,

[Your Name]
