Notifications: text overlaps when text-scaling-factor > 1.0

[sporteka2]

Description

When increasing text scaling (text-scaling-factor) through the Cinnamon settings (Settings → Fonts → Text scaling), notifications display incorrectly — lines overlap each other.

Steps to reproduce

1. Open System Settings → Fonts
2. Set "Text scaling" > 1.0 (e.g., 1.6)
3. Wait for any notification (or send one via notify-send)
4. Observe that text lines in the notification overlap

Expected behavior

Text in notifications should properly adapt to the scaling factor (increase without overlapping).

Actual behavior

Text lines overlap. The notification container does not set line-height, and the block height does not adapt to the text scaling.

Environment

• Cinnamon: Cinnamon 6.6.7
• Theme: Mint-Y
• Font: Ubuntu 10
• text-scaling-factor: 1.6

Diagnosis

gsettings get org.gnome.desktop.interface text-scaling-factor
→ 1.6000000000000005

/usr/share/cinnamon/theme/cinnamon.css → #notification-body has no line-height

Workaround

Reduce text-scaling-factor to 1.0–1.25 or add custom CSS:

#notification-body {
  line-height: 1.5;
}

Sorry you are going to have to post in English.

Apologies for posting in Russian. Here is the translated description:

Summary: When text-scaling-factor is set above 1.0 via Cinnamon Settings → Fonts, notification text lines overlap each other because #notification-body has no explicit line-height.

Screenshot: Shows the overlapping text at text-scaling-factor 1.6:

Environment: Cinnamon 6.6.7, Mint-Y theme, Ubuntu 10 font.

Sorry for the initial post in Russian! I have since translated the entire issue to English (both the description and the comments).

Could you please reopen this issue? The problem is clear:

• Setting text-scaling-factor > 1.0 via Cinnamon Settings → Fonts causes notification text to overlap because #notification-body lacks line-height.
• This is reproducible with Cinnamon 6.6.7, Mint-Y theme, Ubuntu 10 font.

Thank you!

It doesn't seem to reproduce with cinnamon-6.7.x

[sporteka2]

I'm on Linux Mint 22.3 Zena with cinnamon 6.6.7 (pre-installed). I cannot upgrade to 6.7.x until the next Mint release. The bug is reproducible on 6.6.7 with gsettings set org.cinnamon.muffin text-scaling-factor 1.6.

Could you please check if this affects 6.6.x as well?
