Public bug reported: Setting fractional scaling between 125% and 175% yields improper behavior. When set to 125%, display will be scaled to 200%. Attempting to use either 150% or 175% scaling causes gnome-control-center to segfault. Selecting 200% scaling exhibits proper behavior.
Steps to reproduce the issue: 1. Enable the Fractional Scaling toggle under Displays in gnome-control-center. 2a. Select 125% beside Scale, and press "Apply" at the top right. Display should scale to 200% and the selected scale should also change to 200%. 2b. Select either 150% or 175% beside Scale and press "Apply" at the top right. Monitor may possibly turn off for a few seconds, and gnome-control-center will have segfaulted with scaling remaining at 100% when it turns back on.
