SUMMARY
I've noticed a weird font issue in Konsole in a recent-ish update, it makes the font width change when selecting text

I've bisected it to be76d4a2480fbf24e261cf3bf0f69a781100d534, reverting that commit fixes the issue.

I'm using Berkeley Mono, which is sadly a paid font: https://berkeleygraphics.com/typefaces/berkeley-mono/

In the commit that causes the issue, it says the following:
    Enabling hinting does not achieve the desired results (integer width fonts). 
    It helps with some fonts, but makes the situation worse with others.

If this is the case, maybe adding an option to Konsole for full font hinting would help users who are experiencing this issue.


STEPS TO REPRODUCE
1. Open Konsole after be76d4a2480fbf24e261cf3bf0f69a781100d534
2. Select some text
3. See the font warp in width

OBSERVED RESULT
Font width changes in the selection

EXPECTED RESULT
Font shouldn't change width in selection
