Description
What version of the Codex App are you using (From “About Codex” dialog)?
OpenAI.Codex 26.915.4065.0 (ChatGPT.exe product version 153.0.8010.48)
What subscription do you have?
Not specified
What platform is your computer?
Microsoft Windows NT 10.0.26200.9457 x64
What issue are you seeing?
When ChatGPT Desktop (Codex app) is maximized, the window extends below the usable Windows work area and renders behind the bottom taskbar. Because the taskbar is translucent, the app's white background shows through as a persistent milky/blurred horizontal strip across the bottom of the screen. The artifact is visible in the attached screenshot.
What steps can reproduce the bug?
- Use Windows with the taskbar positioned at the bottom and translucency enabled.
- Open ChatGPT Desktop.
- Click the maximize button in the window controls.
- Observe the bottom edge: the app extends behind the taskbar and produces a white blurred strip through the translucent taskbar.
- Restore the window to a non-maximized size; the strip disappears.
What is the expected behavior?
A maximized window should be constrained to the Windows working area and stop at the top edge of the taskbar. No application background should render underneath a visible taskbar, and no white blurred strip should appear.

Research direction
Reproduce the issue on Windows with a bottom translucent taskbar, using the reported 1536×960 display and 1536×912 work area. Start by locating the desktop window maximization and Windows work-area handling; done means a maximized window stops above the taskbar and the translucent taskbar no longer shows a white strip.
