I suspect this might be a bug, but I suddenly noticed that GPT-4o opens a kind of canvas within the normal mode (without the canvas interface). It’s used for text writing and makes GPT-4o almost unusable.
Some examples:
The canvas is often incomplete.
Text gets edited somewhere in the canvas without considering the full context, which often leads to duplicated or completely incorrect text.
It is really slow
The display effect is often completly bugged its kinda text inside text
I tried using it. It immediately condensed my text (yes, I know about the “make longer or shorter”, but it should have printed my text and allowed me to decide what I wanted). As I added content, it got truncated. When it suggested that the text be broken into segments, it produced the entire text instead of the segments. It ignored my request to print in segments three times. It diverged from my story adding ridiculous content instead of printing what I had written. It changed the names of people, though I provided the names to use. I ended up deleting the entire chat. Wont use it again.
