Windows taskbar with auto-hide overlaps the bottom of the Codex composer
What version of the Codex App are you using (From “About Codex” dialog)?
26.727.6591.0
What subscription do you have?
20/month
What platform is your computer?
Microsoft Windows NT 10.0.26200.0 x64
What issue are you seeing?
When the Windows taskbar is configured to automatically hide and the Codex window is fullscreen or maximized, the taskbar does not reliably hide or Codex does not recalculate its usable window height when the taskbar appears. The taskbar can remain over the bottom of the Codex window and block part of the message composer/text box.
Turning taskbar auto-hide off makes Codex snap correctly above the permanently visible taskbar, which suggests the app is not handling the dynamic Windows work area correctly when auto-hide is enabled.
What steps can reproduce the bug?
- On Windows, open Settings → Personalization → Taskbar → Taskbar behaviors.
- Enable “Automatically hide the taskbar.”
- Open Codex and make the window fullscreen or maximized.
- Use the composer near the bottom of the window and reveal the taskbar.
- Observe that the taskbar sometimes remains visible over the Codex window, covering the lower portion of the text box/composer.
Reproducibility: intermittent, but repeated during normal use.
Control test: disabling automatic taskbar hiding causes Codex to snap above the taskbar correctly.
What is the expected behavior?
Codex should keep the entire composer accessible when Windows taskbar auto-hide is enabled. When the taskbar appears, the app should respect the current usable work area or otherwise ensure that the composer is not covered. When the taskbar hides again, the window should recover cleanly without requiring the user to resize or toggle fullscreen.
Additional information
This is on an OLED monitor, where taskbar auto-hide is intentionally enabled to reduce static UI exposure and burn-in risk. Disabling auto-hide is therefore not an acceptable long-term workaround.
