kompare not highlighting intra line differences. Bold text not shown. Problems with kompare and fonts

[Ganton]

Dear Sirs:

I suppose that you already know that, although I've looked for a bug report but it didn't appear:

Using Kubuntu 16.04 this problem is seen: "kompare not highlighting intra line differences". There are more details in: https://bugs.kde.org/show_bug.cgi?id=329912

In the former Kubuntu LTS release (Kubuntu 14.04): kompare uses the "DejaVu Sans Mono" font by default, and kompare correctly highlights intra line differences. But in Kubuntu 16.04 LTS, using kompare an Oxygen font by default, the aforementioned problem is seen.

Perhaps Kubuntu 16.04 LTS should include an Oxygen bold font? Or in Kubuntu 16.04 LTS another font should be used in kompare? Or maybe is something that kompare should solve and highlighting should work using a normal font? Or is a problem in another component? (please feel free to move this bug report to another category :-) )

The problem still happens using Kubuntu 18.04 LTS. This time the Hack font is used by default.

In Kubuntu 14.04 LTS: kompare used the "DejaVu Sans Mono" font by default, and kompare correctly highlighted intra line differences.

In Kubuntu 18.04 LTS: if users manually configure kompare to use the "DejaVu Sans Mono" font, then kompare correctly highlights intra line differences. But users aren't told about it, and the problem is seen.

The problem is not seen using Kubuntu 22.10, thanks.
