--- Comment #4 from Philip Nystromer <philip.nystro...@telia.com> --- This is probably a bug in the way KDE determine the System default settings for my particular screen and monitor. I have managed to apply a manual setting under Applikcation Launcher -> Settings -> System settings -> Fonts, as follows KDE Application Menu -> Settings -> System Settings -> Fonts -> <check the Force Fonts DPI button> and set it to 120 and KDE Application Menu -> Settings -> System Settings -> Fonts -> Use Anti-aliasing -> <change this from "System settings to" Enabled"> then proceed from there into the Configure... menu and experiment with RGB etc settings. For me it worked with: "Exclude range tick box": <Unchecked> "Subpixel rendering type": <RGB>" "Hinting style": <Medium> I think the root cause is that the KDE 5 Plasma suite, together with Xorg does not recognize the type of screen and monitor monitor I have and set the Font System Default settings accordingly. My screen is high resolution 2560x1440 pixel 14" monitor (Computer is Lenovo X1 Carbon laptop, type 20A7-005KMS) -- You are receiving this mail because: You are watching all bug changes.
