Text box lagging when typing inside
Hi NikolinoDE
I had suspected that the lag came about with the introduction of AI, as if Excel were planning to offer some miraculous improvement to the formula but changed its mind. I assume you consider that unlikely?
You’re not the only one who’s noticed performance changes since Microsoft began integrating “Copilot” and other AI features into Office apps.
But I think it is very unlikely that the delay is directly caused by the AI or the copilot logic.
The AI integrations (like Copilot, formula suggestions, and autocomplete previews) run mostly in the background and are not active inside drawing objects such as text boxes.
However, you’re right that lag began showing up around the same time Microsoft started rolling out these AI-related updates.
Hypothesis...in my opinion
Excel AI or Copilot trying to “interpret” text box input interact with text boxes
I Think its very unlikely. AI features don’t interact with text boxes.
Rendering engine update related to Copilot rollout
Same subsystem, causes lag on some setups, can be likely.
GPU/Display scaling issue
Hardware acceleration & DPI scaling are top culprits.
You could perhaps try to temporarily disable Copilot and all online intelligence functions completely (without losing Excel access) – just to see if the performance improves...just a thought🙂
