From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This Week in KDE Plasma: Better fractional scaling (blogs.kde.org)

This week's headliner change is something that I think will make a lot of people happy: better fractional scaling! Vlad and Xaver have been hard at work to snap everything to the screen's pixel grid, with the effect that using a fractional scale factor now results in a lot less blurriness as well as no more gaps between windows and their shadows. You'll see it in the screenshot below (which was taken at 175% scale) but the effects are subtly better everywhere. Really great stuff! And lots more too, of course.

SHHH! Don't tell Gnome that there are options other than 100% and 200%.

[–] [email protected] 3 points 1 week ago* (last edited 1 week ago)

My Gnome has everything between 100% and 350% in 25% increments?

Is this why steam is blurry on gnome?

[–] [email protected] 18 points 1 week ago (1 children)

Not really. The reason is that Steam (and an unfortunate number of other programs) run through Xwayland when your compositor is using Wayland. If you then use fractional scaling, Xwayland will render at the fractional of your resolution and will be scaled linearly to your display. This results in general bluriness for X11 applications.

Kwin, to my knowledge, is the only Wayland compositor that allows decoupling Wayland scaling from Xorg (and does so by default). While this results in different scaling behaviour for X11 apps, it does mean they are never blurry.

If you then use fractional scaling, Xwayland will render at the fractional of your resolution and will be scaled linearly to your display.

This has recently been fixed:

A hidden experimental flag isn't "fixed." It might be the start, but until it's stable and usable through the normal UI, it's not really done.
