looks normal to me. That's how scaling works in wayland by default. Firefox IIRC uses fractional scaling nowadays (or do you need to enable it in prefs?) but in general it looks ok |

@vaxerski but sometimes (mainly when changing from one monitor to another) it gets the size wrong, it only happens in firefox so I'm not sure it's an hyprland only problem. It's very annoying cause it renders the window cropped or leaves some transparent gaps in the sides (depending on the size firefox "thinks" the monitor has). |
