What issue are you seeing?

The Codex Desktop floating pet/avatar overlay is clipped. Only the upper-left portion of the avatar and notification bubble is visible.

This happens with both:

• A custom pet
• Codex built-in pets

So the issue does not appear to be caused by a custom spritesheet or pet.json. It also reproduces on both an external monitor and the built-in Mac display.

• App: Codex Desktop
• Version: 26.429.30905
• Bundle version: 2345
• Platform: macOS
• Display setup: Reproduced on external monitor and built-in Mac display

What steps can reproduce the bug?

1. Open Codex Desktop on macOS.
2. Enable/show the floating pet/avatar overlay.
3. Select either a built-in Codex pet or a custom pet.
4. Observe the floating overlay on screen.
5. Try moving between an external monitor and the built-in Mac display.

Result: the pet/avatar and notification bubble remain clipped.

What is the expected behavior?

The floating pet/avatar overlay should show the full mascot and the full notification bubble, with the overlay window sized to fit the rendered content.

Additional information

Local inspection suggests a mismatch between the avatar overlay's rendered/measured size and the default size expected by the main process.

Persisted global state recorded the avatar overlay mascot/anchor size as approximately 80x87:

{
"electron-avatar-overlay-bounds": {
"width": 356,
"height": 320,
"anchor": { "width": 80, "height": 87 },
"mascot": { "width": 80, "height": 87 }
}
}

However, the bundled avatar overlay code appears to use a default mascot size around 112x121:

gO = { width: 112, height: 121 }

The avatar CSS also implies a roughly 112px-wide mascot:

.codex-avatar-root {
aspect-ratio: 192 / 208;
width: 7.04rem;
}

The overlay wrapper appears to use Tailwind size-20, which is about 80px:

"relative flex size-20 cursor-interaction ..."

This may cause the renderer to report an 80px-ish element size via avatar-overlay-element-size-changed, after which the main process persists/reuses a too-small overlay geometry. The result is stable window-level clipping.

Make the avatar overlay wrapper, sprite root CSS, and main-process default mascot geometry use one consistent size.

For example:

• Avoid constraining the mascot wrapper to size-20 if the sprite/default layout expects about 112x121.
• Measure the actual .codex-avatar-root rendered size instead of the smaller wrapper.
• Clear or migrate persisted electron-avatar-overlay-bounds if invalid small bounds were saved.
