Window resizes automatically to push text prompt box below the screen

Hi. I am running Version 1.2025.217 (1754957881) on macOS Tahoe (26.0 Beta (25A5327h)). Every time the app loads a conversation it resizes the window to the full height of the screen and repositions itself at the top and bottom edges. If I type a prompt and hit send, the window then expands a second time, pushing the text prompt box off the bottom of the screen. I’ve never seen this in previous versions of ChatGPT.

I have been experiencing the same issue since this afternoon (around 6:00 PM SGT). The identical problem is occurring with the same version (Version 1.2025.217 (1754957881)) and GPT-5. Loading times have become significantly longer, and the interface has become unstable, sometimes suddenly expanding to its full extent or behaving unpredictably.

hi all, this is Richard

our team doesn’t care about these bugs or fixing them, so please stop reporting them guys

I am currently experiencing the same problem, and it also stop responding occasionally.

Same problem here. Please fix it asap, otherwise the desktop version is unusable

I agree. It feels like testing wasn’t done properly on this version. I’ve reported three different bugs this morning on this one version of ChatGPT. All of them are more then just a “minor annoyance”.

I’m experiencing the same behavior. The UI is completely non-functional. Please fix it.
(MacOS 15.6 (24G84), M2, app version: 1.2025.217 (1754957881))

Same issue here. Updated to ChatGPT 1.2025.217 today and the chat window auto-resizes, pushing the message input bar below the screen, so there is no way for a user to input. This happened immediately after installing the update, of 3 machines running the app is only happening on the Mac where the update was installed, and a restart of the system / ChatGPT app does not fix the issue.

MacOS Sequoia 15.5 on Mac Studio with ChatGPT 1.2025.217 App for Mac

Same. Especially problematic as a frequent user of Mission Control on my Mac for multitasking. The expanded window forces all the apps to become microscopic in Mission Control. Please fix!

I’m experiencing this same issue - it makes the desktop app on Mac completely unusable. I’m on Version 1.2025.217 (1754957881)

plz halp thx

Same here, it is terrible, an unworkable nightmare.

Come on guys: who developed this?

Oh, of course: ChatGPT.

Experiencing the issue as you describe. It is making the MACOS version unusable now.

Experiencing the same issue in MacOS Sequoia 15.6 on Version 1.2025.217 (1754957881). The issue persists across multiple display and window sizes.

As reported, it makes it very difficult to use the application.

same. on Mac using Mission Control. text input box keeps bouncing below the screen.

MacOS 15.4.1 (24E263)

ChatGPT: Version 1.2025.217 (1754957881)

I am experiencing the same issue. I’m on M3 Macbook Air, Sequoia 15.6, ChatGPT Version 1.2025.217 (1754957881)

Same issue. It’s annoying.

Same issue, I ended up just using the internet site.

Same issue, happens every single time I receive a new output and resizing it only works until I submit the next prompt

Same thing is happening to me. It’s a nghtmare!

They pushed an update to the MacOS app, I have Plus plan. The input area bug is fixed, and 4.0 model is available as well as new 5.0 model variants.
