The current cursor theme does not really seem to fit with other Breeze UI elements. This is rather prominent when it comes to the colors used for some cursors.
Also the overall style and design paradigm might be a bit off. I think they are somewhat derived from Oxygen cursors?
This has already been brought up by me at the Consistency BoF at Academy 2020. Views on this were mixed.
For comparison and inspirational purposes:
Current Breeze cursors: {F9608837}
Yaru cursors (Ubuntu): {F9608838}
Windows 8.1 cursors (almost identical to Windows 10): {F9608839}
I propose to overthink the current cursor theme and identify aspects that are inconsistent / need changing to fit with the general UI of Plasma / KDE.
This is a spin off from https://bugs.kde.org/show_bug.cgi?id=428788.
