XRandr output: 1920x1080 60.02 + 60.01* 59.97 59.96 59.93 The KCM however says my refresh rate is 120 Hz: https://i.imgur.com/cdfgj8z.png The drop down lets me choose between 60 Hz and 120 Hz. STEPS TO REPRODUCE 1.Open Display Configuration KCM OBSERVED RESULT Reported refresh rate is 120 Hz. EXPECTED RESULT Reported refresh rate is 60 Hz. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.17.0 KDE Frameworks Version: 5.63.0 Qt Version: 5.13.1 ADDITIONAL INFORMATION This is under X11 and I don't remember having this issue prior to 5.17.
I'm seeing the same on my laptop which also only has 60 Hz. I also saw that before 5.17 in the old KCM.

There's no drop down anymore, it just says 60 Hz is the only rate the laptop reports so I'm going to say it got fixed along the way.
