The usual question. Was working, not working now, what changed ?
A macOS update (to bigsur which is causing all sorts of problems) ?
The Gimp update to macOS 2.10.22 rev3 ?
Hardware changes - dual monitors for example.
Several reports of offset-cursor problems but nothing very recent.
As well as previous advice, try changing the whole theme to 'System' in Edit -> Preferences -> Themes
Try a revert to an earlier version of Gimp. 2.10.14 is there: https://download.gimp.org/mirror/pub/gimp/v2.10/macos/
A different version of Gimp 2.10.22 - https://www.partha.com/
