Let me guess... You're running an X.Org based WM/DE?
X11 Doesn't support fractional scaling properly . So some DEs will simulate it by scaling the apps the same way you scale a rasterized image like a PNG or JPEG, and as a result everything looks blurry. You'll generally also have the same issue with XWayland apps on a Wayland display.
The best way to combat this? Try to use Wayland native apps as much as possible.
2nd best? Use non fractional values for scaling (x1 or x2 instead of x1.25)
Na, using Wayland with Gnome 45. 1.25x scale actually looks less blurry than 2x. (Putting aside that 2x is ridiculously large.)
Is to buy a laptop with a regular DPI display and avoid this class of bugs altogether. This way I can keep using Discord and 1Password.
Interesting, if it's a native Wayland app, I'd guess the issue is just gnome problems then - from what I hear gnome is one of the poorest DEs for Wayland use, mainly because they refuse to support things the same way that everyone else agrees to, if at all. And they take a fair amount longer to deliberate and agree how to implement anything they do decide to support.
I'd think of looking at KDE, which is very functional at this point, or a wlroots based Compositor/WM, - hyprland seems like one of the more well supported window managers out of the ones using wlroots.
I am using Gnome with Wayland and a 1440p display, and it seems to work surprisingly well. Or maybe I jut got used to dealing with the problems, and would be surprised at how well things work under a different DE.
Do you remember making any tweaks? I had Debian 12 with Gnome and could not figure out how to fix blurred fonts with 1440p display.
I'm on opensuse tumbleweed. It might just be that all the apps I use are Wayland. I'll take a look when I'm back home, currently I'm on a trip visiting family.
Thanks!
Xwayland apps (running in legacy xorg) are extremely blurry under fractional scaling, native wayland apps can have worse rendering but not very noticeable.
The easiest way of checking if you have doubts is install xeyes and launch it. if xeyes follows the cursor inside the app you are tesing is in xwayland, if not is pure wayland.
Electron apps have to be configured to use wayland, whereas If you are in Debian check Firefox (ESR) is using wayland or install it through the offical deb repo of mozilla the latest. I think in the archwiki are the envronment variables to check.
And, for 125% maybe is just worth to you to just scale text to 1.20 using gnome-tweaks and leave it at 100% the scaling. It is not fancy, but it works. I have to use 150% so is too obvious/ugly to just scale the fonts....
Yeah I've heard that xwayland is not great. But I did not have any factorial scaling, just normal 100%, nevertheless I did test esr and the standard one, though the standard is definitely a flatpack. Also just the text on the settings window was blurry so I don't think that was the issue.
