What version of the Codex App are you using (From “About Codex” dialog)?

26.426.12240

What subscription do you have?

Pro

What platform is your computer?

Win11

What issue are you seeing?

Codex begins freezing upon chats with multiple image generations. I am working on a project and using the /image generation skill a lot. Once the chat reaches around 10-20+ images, the chat consistently freezes for about 30s - 1 minute upon sending a new message, or receiving a message from codex. My solution has been to archive the chats after this becomes too much of an issue and begin a new one.

What steps can reproduce the bug?

Chat with around 10+ generated image assets, send a new message or receive a new message.

What is the expected behavior?

30s - 1 minute freeze upon chat with many images created via /image generation skill.
