The Mozilla Firefox 146.0 release binaries are now available with a very exciting improvement for Linux users relying on Wayland.

With Firefox 146, the most exciting change for this last browser release before the holidays is: "Firefox now natively supports fractional scaled displays on Linux(Wayland), making rendering more effective."

Yes, Firefox on Linux is now natively supporting fractional scaling on Wayland!

Excellent news! Now I need to find a Linux distro that has fractional scaling built in so I can see stuff on my giant screen for everything else not in Firefox

more recent kde and gnome versions handle it quite well

[–] 1984@lemmy.today 15 points 4 days ago

Plasma, gnome, cosmic... All the major ones have it.

KDE on cachyos

Fedora gnome and I think kde handles it well too

I think it's been available but hidden in Gnome for quite a while now, yeah.

[–] gustofwind@lemmy.world 3 points 4 days ago (2 children)

Some distros are preconfigured with it hidden some have it shown

No idea why they don’t all have it 🤷‍♀️

From what I can tell, the performance cost was too great until recently, but I forget what they changed to make it suck less for games. I still don't use it because it causes what I can only describe as "weirdness" with resolutions in games, though.

It's disabled by default upstream as it's still considered experimental, some distributions choose to override the upstream default.

Works just fine, OOTB, on Debian with GNOME (I'd imagine KDE as well)

Very cool! A while ago I found that instead of using fractional scaling, things were smoother for me if I set Gome's text scaling factor in accessibility settings. I think most GTK UI scales based off that value? It's pretty helpful for me, even though I'm not actually using Gnome anymore. But if fractional scaling support has gotten better, maybe I'll switch my approach.

It has gotten better in Wayland. I am looking forward to the near future when we can finally stop appending “on Wayland” to everything.
