--- Comment #7 from pk pimk1n@gmx.com --- I retested with F32 KDE as this is when issue started, and thought it might predate freetype 2.10.3 you mentioned, which it does.
This issue is present in all KDE spin releases since F32, it is present in F33 and F34. It is not present in F34 Gnome. Adding the lcdfilter symlink under the Gnome workstation does nothing that I could see, but give noticable quality improvement under KDE spin. This brings KDE spin back to parity with prior releases, and other KDE distrobutions.
You can reproduce just by booting a KDE spin iso and opening Firefox.
Thanks for replying.
