I just upgraded from KDE 4 to KDE 5 Plasma. Since I have good resolution on my screen (2 560 x 1 440, Lenovo X1 Carbon Laptop) I wanted to enlarge the fonts. . After these operations two things happened: 1. The Fixed Width font options no longer contain Noto Sans font, which was the default for Fixed Widht when I entered the menu. 2. Some fonts, notably in KDE applications such as Dolhpin, the KDE Application menu, the clock figures, the font in the konsole, etc do not render properly any more. They are green tinted and very fuzzy. No matter how I try to change the fonts back to normal, I can not get rid of the problem. See screen shots At some point in changing font sizes I also A tried to temporarily switch Look and Feel (System Settings -> Workspace Theme -> Look and Feel) to Oxygen and then back to Breeze. I do not know if this triggered the font problem. Reproducible: Always Steps to Reproduce: 1. Permant problem 2. 3. Rebooting does not help I have created a new user to see if the problem persist - and it does. The problem persist no matter how I try to switch between Look and Feel options, desktop themes and fonts. I consider the severity between Normal and Grave. It is very hard to read menus and text in some applications.
This looks like a graphics driver issue. Which are you using?
I believe it is intel (see this link for my complete Xorg.0.log http://pastebin.com/M6r8T7fM) # lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) # cat /var/log/Xorg.0.log | grep LoadModule [ 10.196] (II) LoadModule: "glx" [ 10.211] (II) LoadModule: "intel" [ 10.214] (II) LoadModule: "modesetting" [ 10.215] (II) LoadModule: "fbdev" [ 10.215] (II) LoadModule: "vesa" [ 10.226] (II) LoadModule: "dri2" [ 10.226] (II) LoadModule: "present" [ 10.347] (II) LoadModule: "evdev" [ 10.368] (II) LoadModule: "synaptics
Graphics chip is Intel HD Graphics 5500
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)
Does this still happen to you in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version)?
