Unlike Windows, with SDL we need to switch the mouse into relative mode to get relative input, which hides the cursor. We do this in-game if mouse control is enabled, and during control mapping.
However in the latter case, we failed to disable it properly when exiting mapping. And also we accidentally saved the state across sessions.
Both problems fixed. Thanks to Aetheros on Discord for detailed reporting.
