I don't see that problem on Tilix v 1.9.4 on Plasma
In the Fonts settings for plasma - Fixed width I'm using Hack 10pt
In my default profile for Tilix I have "custom font" checked and am also using Hack 10pt

What font are you using that profile?

thanks for the reply. For me, the _only_ font that renders properly is hack, every other font i try has the same issue, including the default font. Could you confirm?

Sorry for the really late reply. I just noticed the task had an update.
I had to look, to confirm, is Source Code Pro the default font on tilix now?

I checked quite a few fonts in tilix and konsole. All of the monospace fonts I looked at in tilix displayed OK for me. These are the ones I checked:

Fira Code Medium - ok ✅

Garuda Regular - not ok ❌ (not a monospace font)

Source Code pro - ok ✅

Inconsolata Powerline - ok ✅

Kinnari Regular - not ok ❌ (not monospace)

DejaVu Sans Mono - ok ✅

Liberation Mono for Powerline - ok ✅

Interestingly enough, the fonts that looked bad in tilix aren’t available in konsole’s preferences unless I check “show all fonts”. Without that checked, konsole only shows fonts it considers to be monospace. The ones that look good are available without this being checked.

It looks like tilix is showing all or most fonts, not filtering out the non-monospaced ones.

What monospace fonts aren’t displaying properly on your system? I’d like to try them on mine.

Hey @joebonrichie , is this still an issue on your system?
