[Windows App] Full access warning is transparent and overlaps task content

What version of the Codex App are you using (From “About Codex” dialog)?

26.707.12708.0 (Microsoft Store package: OpenAI.Codex_26.707.12708.0_x64)

What subscription do you have?

What platform is your computer?

Windows 11 x64, OS build 26200, 150% display scale, light theme

What issue are you seeing?

The new strengthened “Full access is on” warning above the composer does not visually separate itself from the task content behind it.

The warning uses a very transparent red-tinted background without sufficient opaque fill or backdrop blur. Task text remains visible through the banner and overlaps the warning title and description. The banner also visually collides with the composer because it is pulled downward with a negative bottom margin.

This makes an important security warning difficult to read precisely when the user needs to understand the risks of Full access.

The problem is visible in the current Windows app when task output extends behind the warning. The dismiss button and close icon remain visible, but the warning body competes with the underlying task text.

What steps can reproduce the bug?

1. Launch Codex Desktop 26.707.12708.0 on Windows.
2. Open a task with enough response content to extend close to the bottom composer.
3. Select Full access so the strengthened warning appears above the composer.
4. Scroll or remain near the bottom of the task.
5. Observe that task text is visible through the warning background and overlaps the red warning text.

The issue was reproduced at 150% display scaling in the light theme.

What is the expected behavior?

The Full access warning should be visually isolated from task content:

• use an opaque-enough surface or a real backdrop blur;
• prevent underlying task text from bleeding through;
• maintain correct stacking order above the conversation;
• reserve enough layout space so it does not collide with the composer;
• remain readable at common Windows scaling factors such as 150%.

Additional information

Inspection of the installed webview bundle locates the component at the message IDs:

• composer.fullAccessWarning.title
• composer.fullAccessWarning.description
• composer.fullAccessWarning.dismissForSession

The warning container currently includes this class combination:

relative z-0 -mb-8 overflow-hidden rounded-t-3xl
bg-token-input-validation-error-background/20
px-4 pt-3 pb-10

There is no backdrop-blur class or equivalent opaque isolation in that container. The combination of z-0, -mb-8, and a 20%-opacity background matches the observed bleed-through and overlap.

The original screenshot is not attached because it contains task content. A redacted screenshot can be provided if needed.
