Font display issue

[fractioneater]

Describe the bug
The font display of the window title seems to have antialiasing issues (no matter what font), and looks "glitchy."

To Reproduce

1. Press alt + tab
2. Examine the window title text

Expected behavior
The font should display like it does everywhere else: clean and perfectly legible, with hard edges.

Screenshots

Logs
Probably unrelated.

Your Environment

• Extension version: 78
• Operating System: Debian 13
• GNOME Shell Version: 48.4
• Windowing System: Wayland
• Are you using other GNOME Shell extensions?
  • List the other extensions: Blur my Shell, EasyEffects Preset Selector, Hide Top Bar, Quick Settings Audio Panel
  • Can you reproduce the issue after disabling the other extensions? Yes

Additional context
Changing "font hinting" in GNOME tweaks does not affect the problem.
Changing "antialiasing" in GNOME tweaks does not stop the problem from occurring, but it looks different depending on how it is set.
This issue persists no matter which font I am using.

As got the same issue while testing #284 on GNOME 49. You can see it the second time Firefox goes by:
