Fedora KDE Cracks Open: Noto Sans CJK Failure Pinpoints Qt's Font Rendering Flaws
Inconsistent CJK font weighting plagues Fedora KDE Plasma, specifically affecting graphical apps like Dolphin and Strawberry. This problem is separate from a distinct, unrelated glitch causing cut-off uppercase letters in Easy Effects on Nobara Linux.
The source of the CJK failure divides opinion. Some users point fingers at the Qt/KDE framework, arguing the rendering engine is faulty. Conversely, others suggest the Noto Sans CJK font family itself harbors the bug. A key observation from 'hitagi' suggests uninstalling Noto Sans CJK for Droid Sans improves rendering, shifting focus away from the font concept itself. Furthermore, the problem seems confined to the Qt toolkit, as GTK apps and Firefox render CJK characters correctly.
The weight of the discussion points to a deep, system-level toolkit issue. While multiple factors are proposed, the most pointed technical insight suggests the failure is localized to the Noto implementation within the Qt environment, requiring advanced `fontconfig` debugging rather than a simple font change.
Key Points
CJK font weights are inconsistently thick (Kana/Hangeul appear heavier than Kanji/Latin).
Observed by 'hitagi' in graphical KDE apps like Dolphin and Strawberry on Fedora 43 KDE.
The CJK issue might be limited to the Qt toolkit, not the entire desktop environment.
Multiple sources noted that GNOME/GTK apps and Firefox render CJK characters correctly.
Changing the system font to 'Noto Sans CJK Light' bypasses the weight issue visually.
Suggested by 'hitagi' as a functional workaround for KDE/Qt.
The font malfunction might stem from the Noto Sans CJK package itself.
Suggested by preliminary observations and supported by 'hitagi' when Droid Sans provided improvement upon Noto removal.
The Easy Effects cut-off letter bug is an independent problem.
Mentioned in the context of troubleshooting the unrelated font rendering glitch on Nobara Linux.
