same issue on m4 mac mini :( macos 15.2

[achenjiefeng]

It's not just a mouse issue; the keyboard section also has incompatible key mappings, which is likely because moonlight or sunshine hasn't been adapted for macOS.

can confirm, 13.6

It's not just a mouse issue; the keyboard section also has incompatible key mappings, which is likely because moonlight or sunshine hasn't been adapted for macOS.

I'm experiencing the same issue. For example, when I press the Command key and then another letter key, the letter key sometimes gets stuck and doesn't release.

The Mac mini M4 Pro using sunshine-beta v2025.414.181259 to stream to Windows 11 via moonlight also encountered the same issue, which appears to remain unfixed.
The Mac's scroll wheel event coordinates do not align with Windows' default expectations, causing Sunshine to interpret vertical scrolling as a mixed input of tilted X/Y axes (manifesting as diagonal scrolling). This is a compatibility issue with Sunshine's input mapping module.
Mac mini M4 Pro使用sunshine-beta v2025.414.181259串流至win11的moonlight也出现了同样的问题，看样子一直没修复。
Mac 的滚轮事件坐标与 Windows 的默认预期不一致，导致 Sunshine 将垂直滚动解析为 倾斜的 X/Y 轴混合输入（表现为右下滚动）。这是 Sunshine 输入映射模块的兼容性问题。

Was told to comment here from the discord.

I'm also seeing this from Windows/Android Moonlight clients to a MacOS Tahoe 26.2 host running Sunshine (2025.924.154138 commit: 86188d4).

When using the scroll wheel on a box that can be moved in both the x and y directions (the logs box in the sunshine web app, for example), if I scroll up, the box moves in an up and left direction (-x,+y). If I scroll down, the opposite happens and it goes down and right (+x,-y).

I've attached video/logs to the thread in Discord (https://discord.com/channels/804382334370578482/1461851099341258855).
