Text is blurry in apps like edge, spotify etc. But not blur in system apps , firefox.

I recelty upgraded from F38 to F39. In F38 i was using default settings for display which is 2880x1800(16:10), 90hz,200% scaling. AFter upgrading to F39 when scaling is set to 200 percent texts are blurry in apps except system apps and firefox. If i set scaling to 100 percent and increase font scaling from gnome tweaks application texts are not blurry.
my graphic card is Intel iris xe. Please let me know if there is any fix for it. btw i use wayland system

telegram is fine too in 200percent scaling in F39.
I am using gnome desktop environment

This is caused by fractional scaling, which kicks in even for integer
multiples now:

The workaround is to disable fractional scaling. There should be a toggle
in GNOME Settings, but it's not there yet at this moment. You can see how
to disable it manually at the end of this article:
https://www.omglinux.com/how-to-enable-fractional-scaling-fedora/

We probably need to create a Common Issue description for this.

thank you for the reply!
gsettings set org.gnome.mutter experimental-features "[]"

i have executed this command in terminal with/without sudo access. Even after rebooting it , blurry text still remains and also i can see non integer scaling options too 100,125,150,175,200 ...

You shouldn't run this with sudo, just as a regular user. What do you get
if you run
$ gsettings get org.gnome.mutter experimental-features
?

Here's how it should work:
$ gsettings get org.gnome.mutter experimental-features
['scale-monitor-framebuffer']
$ gsettings set org.gnome.mutter experimental-features "[]"
$ gsettings get org.gnome.mutter experimental-features
@as []
$ gsettings reset org.gnome.mutter experimental-features
$ gsettings get org.gnome.mutter experimental-features
['scale-monitor-framebuffer']

So far, I've only tested in a VM, but the fractional scaling factors
disappear from gnome-control-center once I disable
"scale-monitor-framebuffer". But I'd think relogin is required for app
scaling to actually change.

It is working fine now , after reexecuting the command. Maybe i messed up before. Sorry for the trouble.
Can confirm non integer values are removed from settings and texts are not blurry.
Thank You
