Title:
unity8 stops processing touch input events after holding the palm for
a few seconds on the screen
Status in Canonical System Image:
Confirmed
Status in unity8 package in Ubuntu:
Confirmed
Bug description:
current build number: 403
device name: arale
channel: ubuntu-touch/rc-proposed/meizu.en
Test Case:
1. Boot the phone and unlock it
2. hold your palm on the border of the screen for several seconds (I'm on the
application scope by default)
3. Scroll the page up and down
Expected result
Scrolling works as expected, page goes up/down
Actual result
The dash is like frozen. A right edge swipe works and clears the problem up.
