Hello everyone! I started to use GNU/Linux a week ago or so and I don’t have lot of experience yet, only I know some basics.
I have a problem with font rendering in certain apps. I figure that is an scaling problem but I’m not entirely sure. To give some information, I have 2 monitors, both with same resolution and scale set at 100%, only different refresh rate. Also Anti-aliasing is enabled, sub-pixel rendering set to “RGB” and hinting “Slight”.
(More info if needed: Nvidia Driver Version: 580.95.05 - Fedora 43 KDE - Kernel 6.17.7-300.fc43.x86_64)
So, the fonts of system apps looks good, the problem comes with Firefox, LibreOffice or Discord (to mention some of them), when the Anti-Aliasing doesn’t applies at all in certain scales.

This is an example text in LibreOffice (Pre installed app).
Now look the next screenshot.
Here looks better than the other image, so I think the Anti-aliasing is working as intended (90% scale)

Other thing it gives me a headache, is that this is doesn’t happening with all the fonts, they are some of them. Arial or Times New Roman renders well in this image, but not in Calibri. In Youtube I have same problems with their fonts (Flatpak Firefox), but not here in the forum.
Maybe I imported the fonts bad in the system? I’m dual-booting, so I copied the fonts folder in Windows and pasted it in /home/User/.local/share/fonts/
Setting Hinting at “None”, seems to work. Fonts looks a little blurry but are well rendered. But I’m not having the same luck with Flatpak apps.
Anyone having the same issue? Thanks a lot for reading my first post!
