Bad font rendering in alacritty

[dase78]

I have an issue with lf in alacritty: the rendering of font/bar is not doing well.

I first thought, this is an Alacritty issue but after some testing it seems to me, as it was lf because in other TUIs (cmus, micro), everything is fine. This does not happen in Lxterminal or others, just with lf in combination to Alacritty.

Left pane Lxterminal, right pane Alacritty:

I use Hack Nerd Font Mono. Any ideas?

I forgot: Debian Stable (12), Alacritty 0.11.0, LF 28 (no Build-Environment, Stable Version from official repo)

Does the problem occur with other font? Because I'm also under Debian 12, I installed Alacritty, but I don't see any problems, although I use IosevkaTerm Nerd Font Mono.

Yes, Liberation Mono, generic monospace. It always is this kind of blurish. EDIT: In combination with Alacritty.

Please paste your alacritty conf file (alacritty.yml) without comments.

Rename the alacritty.yml file to alacritty.backup, then restart alacritty and try now.

Yes, it looks a bit "better", but of course not, how I want it to be... Perhaps I will just stick with lxterminal.

So then I can only think that the video card and the driver it can cause this problem, because Alacritty uses GPU acceleration. Alacritty, for example, works well and very fast for me, but the wezterm terminal is very slow, even though it also uses GPU acceleration... That's why I sometimes use urxvt and sometimes st terminal.

Yes, I will stick with Lxterminal. But it's a strange issue, because it's only this special combination: LF + Alacritty.
