I was looking at different apps and settings. 125% scale on Bluefin is VERY clear. I like it a lot. It can stream 4K video from Plex and it looks very nice and runs well. I realized that if I run 125% with the Large Text, it can actually make it feel worse. Now you have nice larger text in GNOME apps mixed with tiny legacy XWayland apps making it very jarring to switch from one window to another. I feel like things were better on Ubuntu, but that’s probably because 125% was a bit blurry so I usually used 150%. I wish I could do side by side comparisons, but I only have one laptop.
On the right, you see GNOME Files with the Accessibility/Large Text setting enabled next to Double Commander, also a file manager, using XWayland and not affected by the Large Text or Scale settings. It gets a bit annoying!
