SUMMARY The new tool for remapping extra mouse buttons is not working for mouse wheel left/right and middle button actions (using Logi Anywhere 2S mouse). Nevertheless left-side buttons are being detected. xbindkeys supports all actions fine, so this is not a hardware problem. STEPS TO REPRODUCE 1. Go to settings > Input Devices > Mouse 2. Select the correct device and push the Re-Bind button 3. Click Add Binding then push the extra button to remap OBSERVED RESULT Not detecting and mouse events SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon 5.27 (Wayland) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION
