SUMMARY Running under Wayland, in touchpad settings, when first opened, the last setting is "Scrolling speed", and "Right-click" and "Middle-click" do not appear (but presumably should). However, when Highlight Changed Settings is pressed, settings for "Right-click" and "Middle-click" appear, function properly, and persist after Highlight Changed Settings is disabled, but not when leaving/returning to the panel. STEPS TO REPRODUCE / OBSERVED RESULT As per summary; consistently happens for me with newly-opened system settings. When highlight changed settings is turned off, the options remain, but when goig to another panel and returning, whether or not highlight changed settings is still on, the options disappear and do not return regardless of changes to highlight changed settings. When present, the settings are completely functional, and the changed settings do persist properly. EXPECTED RESULT These settings should appear for this hardware: I actually found the behaviour while searching for them. It is possible that there are two bugs here: that the settings are being incorrectly filtered out, and that highlight changed settings is breaking that filtering. This may be related to 408116.
