Serious text scaling regression in the latest ChatGPT macOS app

I’m experiencing a serious text-scaling regression in the latest version of the ChatGPT macOS app.

The issue makes the app very difficult, and in some cases effectively impossible, to use for text-heavy work.

The main problems are:

1. The default font size is extremely small The default text size is too small for comfortable reading. It quickly causes visual fatigue and makes long conversations feel tiring to read.

2. Keyboard shortcuts do not work for increasing text size The usual zoom/text enlargement shortcuts do not reliably increase the text size in the chat interface. This makes it impossible to quickly adjust readability from the keyboard.

3. Large inconsistency between normal text and code block rendering There is a very noticeable mismatch between the size and formatting of regular chat text and text inside code blocks. The difference is large enough to disrupt reading and reviewing technical content.

4. Code block text size cannot be adjusted Even when the normal chat text size can be changed, the text inside code blocks does not appear to scale properly. Code blocks remain too small and are not affected by the same enlargement/reduction controls.

5. Text size settings are not preserved when returning to a chat Even if I manage to enlarge the text, when I leave the conversation and later return to the same chat, the display reverts back to the original small size. This makes the adjustment temporary and unreliable.

This feels like a core usability and accessibility issue, not a minor visual preference. Reading, writing, and reviewing text is the central function of the ChatGPT app, especially for users working with code, technical documents, and long conversations.

I honestly do not understand how such an obvious issue made it into a public release. Was text scaling tested before release? Were code blocks, keyboard shortcuts, and returning to existing chats included in the QA process?

Thanks.
