waybar height changes to accomodate unicode emojis in window titles

[llyyr]

The height of the window title text sometimes causes waybar's height to increase (from 17px to 24px in this case). This messes with positioning with sway and such. There should be an option for the height to be fixed, even if it means some text might overflow.

Example emoji that does it: 🎙

Example style.css

* {
  font-family: "Noto Sans Mono"; 
  font-size: 9pt;
  padding-top: 0;
  padding-bottom: 0;
}

Fwiw I could only find two fonts that this is an issue with, Sarasa Gothic, Noto Sans Mono and Iosevka. But waybar's height should remain the same regardless of what the modules do if that's what the user wants.

@Alexays Please address this issue. I can confirm that it messes with sway positioning. It causes all windows to resize. And the worst of all, it occasionally causes my chromium based browser (brave) to freeze when a tab has unicode character that cause the bar to resize to accommodate it. It is just problematic.

[Kacper-Kondracki]

Found a workaround. Setting a negative margins to a module margin-top: -50px; margin-bottom: -50px hacks it, so larger unicode characters no longer change height of the bar.

Your microphone emoji doesn't trigger this bug for me. But this one does:

zenity --title="༺" --entry

@Kacper-Kondracki, it works, but the tray icons disappear for some reason.

Did anyone try some other solutions?

I also observe this behavior. For example when listening to JARYMANE mixes on YouTube. They use a weird symbol in the video titles. For now, thanks @Kacper-Kondracki . But I would happily welcome a more mature solution.

The workaround does indeed help (applied it to #window section of style.css, and did killall -SIGUSR2 waybar), thanks!

It feels like a hack, though. This rather annoying issue should be addressed at systems level -- there should be no physical way for styling/contents to change bar geometry.
