Curious about GNOME fractal scaling issues you experience.

I currently have the experimental feature enable at 150% scale for a laptop screen at 2560x1600 resolution. Have not had any issues by itself nor with an external 3440x1400 at 100% scale with GNOME 48.

I wish I could give you a better answer here, but I honestly don't remember. I only remember that something I needed was missing from it for me to make the switch.
