Most websites with text display random blue letters or blue parts of letters which are supposed to be black. Some have other colors
It started a couple of weeks ago on both Endeavour KDE and my Manjaro KDE after I updated them both. XFCE still displays everything perfectly so it’s not my monitor. I didn’t change any of the fonts recently
Here’s a picture of some text at the top of this page, first the correct render on XFCE and in the second screen capture on KDE you can see a few random blue letters. Does anyone know what’s causing this?
I just ‘fired up’ Firefox, and nothing appears to be different on mine. I’m set to Deja Vu serif (16) and all appears well. I’m on a 4K monitor, though, so that may be affecting (ie: helping) the situation. I saw something similar in another arch-based distro - and the ‘help’ described above cured it (weird colours in small conky fonts)
Note: For some desktop environments (such as GNOME and KDE) using the Font Control Panel will automatically create or overwrite the user font configuration file. For these desktop environments, it is best to match your already defined font configurations to get the expected behavior. Also ensure that the desktop locale settings or Regional Settings are supported by the configured fonts, if not the font configuration could be overidden.
In watching better you screenshot, there is not only blue but red and green around letters, wich means RGB !
Then you could check into /etc/fonts/conf.avail if sub-pixel RGB is enable or not ?
I installed Chromium to check and it rendered fine, so I’ve isolated it to the combination of Firefox and KDE. When I magnify a Firefox browser tab to 120% or higher, the problem goes away for some reason.
The pictures from my first post aren’t really easy to see. I cut a tiny piece of text from the the EOS Wikipedia page and blew it up in GIMP to show some blue letters
