I have installed Fedora 36 KDE 5.25.2, and I am trying to scale the display because the text is very small. However, when I set the display scaling to 125%, the text becomes blurry. I have tried forcing the font DPI to 130, but it doesn’t help much.
I have an Nvidia graphics card with Wayland.
To maybe identify if this is wayland or not you might log in using xorg and see if the scaling is the same or different. Just a first step.
In KDE Wayland scaling has issues with GTK application, I reported my experience and some suggestions here KDE Plasma 5.25 in Arch | Lorenzo Bettini
I switched to Kubuntu, which uses X11 by default, and I don’t have the same issue any more.
You could have simply logged in to plasma in Fedora with X11
Yeah. But I wanted to test Kubuntu with its default settings too (I have both now).
I have other issues with Fedora KDE Wayland. For example, the picture-in-picture does not work reliably in Edge/Youtube and Telegram Desktop. They become dim when I click somewhere else.
