Sublime Text on wayland/kde is blurry

#1

Hello,

I noticed that the fonts and over all quality of sublime text on my PC is very blurry and I don’t know why.
I am using jetbrains mono as my font. when I use other applications the font and screen is not blury at all.

these are my settings,
`
“hardware_acceleration”: “opengl”,
“hot_exit”: “disabled”,
“remember_workspace”: false,

"color_scheme": "Monokai Pro (Filter Spectrum).sublime-color-scheme",
"theme": "Nabla Adaptive.sublime-theme",

"font_size": 18, 
"font_face":"JetBrains Mono Medium",
"font_options": ["no_liga",
                "no_clig",
                "no_calt",
                "no_italic",
                "subpixel_antialias"],

`

I tried no acceleration,no subpixel_antialias, but its still blurry and I don’t know what is going on.
I am using fedora 43 with kde plasma

thanks

That screenshot doesn’t look blurry to me. Does the screenshot itself look blurry to you? If so, can you post a screenshot of text from a different application on your system that doesn’t look blurry.

Do you perhaps have a non-integer scaling on your display? Does the text still look blurry if you change it to an integer scale?

My experience based on working with real 4k vs. HD or WHQL screens is, fonts such as Jetbrains not really being optimized for “low-resolution” displays and related anti-alias or ClearType functionalities. Hence those look disappointingly blurry on HD/WHQL screens compared to 4K screens, especially when using dark color schemas.

At least on Windows however, ST is one of the apps with best font rendering results. The only other satisfying results are provided by Firefox. Chrome based browsers or Electron apps, as well as WinUI3 controls provide way worse font quality.

I switched to Cascadia Code on Windows when working with HD/WHQL screens, which looks way crisper, than Jetbrains.

I did further research and found that my blurry window and fonts have nothing to do with sublime. I am using two monitors, 1440p and 1080p. Furthermore, I’ve found bug reports for scaling issues with either qt/plasma or Wayland. I also found a post about JetBrains fonts suboptimal/broken for Wayland.

I will try other fonts, and update this post if anything changes

You mention Wayland so on Ubuntu. Now when you bootup from scratch just before entering password there is a logo where you can drive different desktop sessions and install them. But be wary because I found that logging into a different session than historic might raise an alarm from some accounts because it looks like a different user profile causing a false rejection. Caused me a lot of problems with an important account being locked. Have your login details for banks etc. ready to apply in the new session should you experiment .
