Edit: the parent commenter does not have a miniLED iPad.

If you have the 12.9” M1 iPad, the ghosting is likely due to the new miniLED backlight which was introduced with that model.

This backlight is not static, but tracks to content in order to increase effective contrast (similar to FALD backlights on higher end LCD TVs). If the backlight does not track the LCD content fast enough, there can be ghosting.

In addition, since the LEDs are large compared to pixels, you can sometimes see haloing, particularly in small bits of white on a black background.

Overall, while the display is great for video, especially HDR video, it has some problems with UI and (white on black) text.

It's on the 11" model, so regular old LCD model, not the new fancy microled.

No issues on my iPad you might want to take it to Apple.

I’m guessing it must be an issue with those new miniLED screens, or some other significant generational problem. I have two older 12.9” iPad Pros, one 1st generation and one 2nd generation (the first with the 120hz display). They are both excellent displays with no such issues with motion or ghosting.
