  **Description:**
  
  After upgrading system packages on Ubuntu 25.04, the window control
  buttons (minimize, maximize, close) appear at inconsistent sizes across
  different GTK applications.
  
- For example:  
- - In **Nautilus** and **GNOME Text Editor**, the window buttons are 
noticeably **smaller**.  
+ For example:
+ - In **Nautilus** and **GNOME Text Editor**, the window buttons are 
noticeably **smaller**.
  - In **GNOME Terminal**, the window buttons appear **larger**, as expected.
  
  **Steps to Reproduce:**
  
- 1. Install Ubuntu using the `ubuntu-25.04-beta-desktop-amd64.iso`.  
- 2. Observe that window button sizes are consistent across GTK apps.  
- 3. Upgrade system packages using the default package manager (`sudo apt 
update && sudo apt upgrade`).  
+ 1. Install Ubuntu using the `ubuntu-25.04-beta-desktop-amd64.iso`.
+ 2. Observe that window button sizes are consistent across GTK apps.
+ 3. Upgrade system packages using the default package manager (`sudo apt 
update && sudo apt upgrade`).
  4. Restart and observe the change in window button sizes across different GTK 
applications.
  
  **Expected Behavior:**
  
  Window button sizes should remain consistent across all GTK apps, before
  and after system updates.
  
  **Actual Behavior:**
  
  After the system upgrade, some apps (e.g., Nautilus, GNOME Text Editor)
  display smaller window buttons, while others (e.g., GNOME Terminal)
  retain larger buttons.
  
  **Additional Info:**
  
- - ISO used: `ubuntu-25.04-beta-desktop-amd64.iso`  
- - This issue was not present in the clean installation, only after the 
upgrade.
