SUMMARY Generally, the user expects that if one executes a gesture, executing the opposite of that gesture will return things to their initial state. This does not currently happen. For instance, one can get to the overview by swiping downwards with four fingers, but swiping upwards with four fingers *while the overview is active* does not close it, but shows a list of virtual desktops. STEPS TO REPRODUCE 1. Execute any gesture 2. Execute the reverse of that gesture OBSERVED RESULT Arbitrary behaviour EXPECTED RESULT Return to initial state
The problem here is that if you swipe up too hard/long, then it not only closes the effect but also does a four-finger swipe up gesture, which triggers the Desktop Grid effect. I believe this is slated to be fixed in Plasma 5.26.
