Re: "iPadOS mouse pointer erratic, Pointer Animations broken
iPadOS 26, mouse pointer keeps growing and shrinking unpredictably, furthermore the Pointer Animations option in Accessibility settings isn't working at all. All the animations are staying including the shrinking and growing."
Seems there are two different pointer settings to check and maybe make changes:
(1) Settings > Accessibility > Pointer control
and then:
(2) To customize the buttons of the pointing device: Settings > Accessibility > Touch > AssistiveTouch > Devices.
Apple support's online article (link below) explains the details
Make the pointer easier to see when using a mouse or trackpad with iPad - Apple Support
Eg: says:
"Make the pointer easier to see when using a mouse or trackpad with iPad
If you have difficulty seeing or following the pointer when you use a mouse or trackpad with iPad,
you can change its size and color so it’s easier to locate on the screen.
Go to Settings
> Accessibility > Pointer Control, then adjust any of the following:
- Increase Contrast
- Automatically Hide Pointer
- Color
- Pointer Size
- Pointer Animations
- Trackpad Inertia (available when a supported multi-touch trackpad is connected)
- Scrolling Speed
To customize the buttons of the pointing device,
go to Settings > Accessibility > Touch > AssistiveTouch > Devices."
