I'm experiencing same problem with same font. It stopped displaying correctly after the latest Ubuntu Kernel update (6.14) - I don't understand how, but it did. Version: 1.0.223, installed as AppImage Platform: Linux (Ubuntu 24.04.2 LTS x64, Kernel 6.14.0-24-generic, Wayland) Plugins: none Frontend: xterm (WebGL)

Here's the screenshot:

Attention!! Bugs are gone when I switch to xterm (Canvas) frontend.

Do you experience this bug after switching from WebGL frontend to Canvas? It fixed things for me.

The Bug is not majorly noticeable when I turn off ligatures and reduce font size under 17, IDK why it worked for me. ( Still on webgl )
