What version of the Codex App are you using (From “About Codex” dialog)?
26.803.81509
What subscription do you have?
Pro
What platform is your computer?
Ubuntu 24
What issue are you seeing?
The Codex Linux app does not appear to fully support Wayland setups with multiple monitors using different DPI/scaling settings.
When moving the Codex window between monitors with different scaling factors, the UI may render at an incorrect scale or behave inconsistently.
Expected behavior:
The app should correctly detect and adapt to the scaling factor of each monitor when the window is moved between displays.
Actual behavior:
Scaling/DPI handling is inconsistent across monitors.
What steps can reproduce the bug?
- Install Codex App on Ubuntu
- Switch from any-dpi to a higher or lower dpi screen
What is the expected behavior?
Like chrome/firefox/vscode apps should scale UI.
