SUMMARY

This bug has always been present in Plasma 6.
When configuring the screen corners for the presentation or desktop grid effect, it often happens that the effect bounces, even if I have set a high value for reactivation.
I report that restarting kwin sometimes seems to solve the problem for a while, only to reappear later.


STEPS TO REPRODUCE
1. Set the presentation effect to the top left corner of the screen and the desktop grid effect to the bottom right corner 
2. With the mouse or touchpad try to activate the effect by moving the mouse pointer to one of the two corners.


OBSERVED RESULT
The effect often (but not always) rebounds


EXPECTED RESULT
It should not bounce.
