Bug ID: 409374 Summary: You can not enable font anti-aliasing with sub-pixel rendering because system settings will automatically put a check mark in the box to block anti-aliasing and make fonts unreadable and you can remove checkmark but gets placed back upon opening and close Product: systemsettings Version: 5.16.2 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: major Priority: NOR Component: kcm_fonts Assignee: unassigned-b...@kde.org Reporter: freefreen...@gmail.com CC: unassigned-b...@kde.org Target Milestone: --- Created attachment 121261 --> https://bugs.kde.org/attachment.cgi?id=121261&action=edit This is how it locks itself after you enable font anti-aliasing SUMMARY In fonts section of system settings for two days in Arch Linux after the latest two batches of KDE updates I can not enable font anti-aliasing because when I do and close out system settings and open it again and then open Dolphin at the same time it automatically puts a check mark in the box for blocking anti-aliasing so therefore it makes fonts completely unusable. This happened and I thought I had a corrupt system so I spent the time to completely reinstall Arch yesterday and it happened again as soon as I turned font anti-aliasing on. I normally use fonts with enabled anti-aliasing and RGB sub-pixel rendering with slight hinting for best looking fonts but the way it is now I can't not enable any of that because when I do enable it then it automatically puts a check mark in box for blocking anti-aliasing and sets it from 1-99. You can go and remove check mark and it puts it back again upon opening a couple apps. One last thing I am not for sure Dolphin has anything to do it with I know if you open and close system settings with Dolphin open it may talke a couple times but this happens for sure. STEPS TO REPRODUCE 1. Enable font anti-aliasing with RGB sub-pixel rendering and slight hinting 2. Close settings and open Dolphin 3. Open System Settings at the same time as Dolphin and you may have to open system setting and dolphin several times but the fonts will become unreadable. OBSERVED RESULT Unreadable fonts EXPECTED RESULT Readable fonts SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Yes (available in About System) KDE Plasma Version: 5.16.2 KDE Frameworks Version: 5.59 Qt Version: 5.13 ADDITIONAL INFORMATION I am on Arch Linux stable and this happened on clean install after I thought my system was corrupt I reinstalled. This is pretty serious bug. -- You are receiving this mail because: You are watching all bug changes.
