Created attachment 107534 [details] example1 This happens when the font used has a light weight variant (e.g. Roboto Mono, Source Code Pro). I don't know if it is supposed to be so, but I find it very hard to read and there is no way to change it in the settings.
Can you explain in more detail what the problem is? Are the variable names too light to read?
Some fonts may come in many different weights (https://en.wikipedia.org/wiki/Font#Weight). For some reason the editor chooses the light font weight for some tokens (variables, control flow keywords, object field access on the screenshot). My settings are: - Roboto Mono is the default monospace font (via fontconfig rules) - KWrite:Fonts & Colors:Font:Monospace:Normal While writing this I've found that if I set a different font via KWrite settings then everything will use the selected weight, even the tokens which should be bold (e.g. keywords). Looks like it may be related to this. Could it be that my font configuration breaks the text rendering somehow? Can someone try to reproduce this?

Thanks for the info.
