Description kabud 2020-05-09 04:55:34 UTC 
SUMMARY
I configured Application Launcher on left and top edge and Show Desktop on right and bottom, but none of them seem to work

STEPS TO REPRODUCE
1. settings - workspace - touch screen
2. set left edge to Application Launcher and Apply
3. swipe inward over left edge of the touch screen

OBSERVED RESULT
nothing happens, or maybe I end up moving a window if the swipe happens to land on the title bar

EXPECTED RESULT
trigger Application Launcher

Comment 3 Zamundaaa 2020-07-09 22:51:21 UTC 
So I played around with the patch on Gitlab that makes the screen edge bigger...
If I make the screen edge 20px big then swiping from the edge still doesn't work but putting the finger directly on the screen edge area and swiping inwards from that does work.
Removing the screen edge though touch inputs are instantly recognized when swiping from the edge, so it's definitely not a hardware problem.
