Created attachment 132476 [details] Preview of bug SUMMARY Clicking fast on the "Highlight changed settings" button doesn't work properly. For example, try double-clicking or clicking a little fast (2 clicks per second) on the button and what happens basically is that the setting doesn't get detected (the option doesn't change state, but the button visually becomes enabled/disabled). It doesn't even have to be really fast continuous clicks; just two clicks within a second triggers it. This is seen in the attached image (the button is visually enabled, but changed settings aren't highlighted). STEPS TO REPRODUCE 1. Open System Settings 2. Keep clicking a little fast on the "Highlight changed settings" button a few times. OBSERVED RESULT The setting sometimes doesn't toggle properly (the button becomes visually enabled/disabled, but the actual state of the option doesn't actually change). EXPECTED RESULT The option's state should properly change with each click of the button.

Can confirm.
I couldn't reproduce at least on Wayland. I tried about five times and double clicking as fast as I could. The result for me always was that the setting got enabled and then disabled again. Do I have to click fast more often then twice? Like three or four times? Have you tried this on Wayland? I also thought maybe you have weaker hardware, but looking at it that is not the case. Are you sure that the click events get recognized when the state doesn't change?
I can also confirm now. Probably I didn't take much attention to what actually should happen when double clicking and thought everything worked fine, sorry about that. One thought is that this might be actually a feature to prevent accidental double clicks?
It's not an intentional feature.
