SUMMARY

On Plasma 5.21.0 there is a bug with the cursor, when I hover on things that
change the cursor (e.g. clickable links, textboxes, edges...), for a
millisecond it revert to the normal cursor with an offset, which makes some
flickering.
The bug affect both Wayland and X11 sessions.

STEPS TO REPRODUCE
1. Move your cursor to texts, edges, anything that change its appearance 
2. Slowly move it around
3. See that it's jumping around

OBSERVED RESULT

The cursor reverts to normal with an offset for a few milliseconds then revert
to a normal position

EXPECTED RESULT
