### Describe the Bug

I'm running https://github.com/Steam-Headless/docker-steam-headless with Moonlight to play EVE Online on my second monitor. Since I use it as a secondary display, I have `Optimize mouse for remote desktop streaming` enabled so the cursor can freely leave the Moonlight window.

The issue is that when dragging the mouse to rotate the camera, it frequently sends the camera into a wild spin, as if I just jeeted my mouse a few meters away.

Start by reproducing the mouse-spin behavior with "Optimize mouse for remote desktop streaming" enabled while streaming EVE Online through Moonlight from the listed Docker/Linux host to the Windows client. The payload names no source file or test, so trace the mouse-input handling from that setting and add a regression test or documented reproduction once the expected camera movement is established.
