I am using the ChatGPT app on the MacOS - Version 1.2024.163 (1718653947)
Mac OS: 14.5 (23F79)
Have a look at the attached screenshot. It is visible that the input field is unnaturally squeezed. I would say it is a UI issue.
I can’t seem to replicate your error on the application, same version: 1.2024.163. I tried on macOS 14 and 15, in fullscreen mode and as minimized as possible:
As you could see, I have chatted and the window is not empty, as it is in your case.
When I first started the app, it was also not broken.
Have you tried restarting the application?
Yes, after a restart, there is no the problem anymore.
