[BUG] B1 se plus bugfix-2.1.x(with stm32f4-tft-spi-fix) feels like there's a noticeable delay

[doshiyo103]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I have tried overlaying the file from #26052 onto bugfix-2.1.x and attempting to rebuild before booting up.
This time, the "marlin mode" appeared, but it led to another issue.
Every step of the operation now feels like there's a noticeable delay. Could you please check and confirm this issue?

I'm sorry to open another issue, but the other one, #26504, has been closed.
