Blur on third-party software (HiDPI) in Fedora34

I am new to Fedora.
When I change the DPI to 150%,
(gsettings set org.gnome.mutter experimental-features “[‘scale-monitor-framebuffer’]”)
everything is in blur on third-party software in Fedora 34.

What is the possible solution?

Don’t use a fractional scale. Even if it is supported by your DE/WM, it isn’t always handled well by applications.

Instead, set the scale back to 1.0 or 100%. Then, increase the scale factor of your font. Although it isn’t intuitive or obvious, most UI elements scale with font size so if you want a scale that it less than 2x, scaling your font will usually yield the best results.


That’s exactly the reason why Gnome allows only 100% 200% 300% 400% scaling. Scaling integers is also better for performance reasons than scaling floats or postprocessing (linear/aniso filtering or AA)
