Our dev team is unable to reproduce the issue you’re having with edits to the mouse performance page not saving. They suggested a full restart of CORE should fix this - for reference, by full restart they mean:
- right-click the CORE window in the Windows taskbar and choose “Close Window,” or use the X to close out of the app
- then visit the system overflow tray, right-click the Glorious CORE logo, then choose “Quit Glorious Core.”
If you try this and still experience issues please let me know and I’ll relay that to them.
