[Bug 1917010] Re: Hard to detect double-clicks on the HiDPI touchscreen system

[Kai-Heng Feng]

Yes, I will accomplish the testing and verification.

However, gnome-shell-extension-desktop-icons gets uninstalled on Impish
because the gnome-shell in -proposed breaks gnome-shell-extension-
desktop-icons (<< 21.04).


** Description changed:

+ == SRU Justification ==
+ [Impact]
+ Double tap desktop icons on a touchscreen barely works.
+ 
+ [Fix]
+ Because tapping isn't as precise as clicking, ignore the double click distance as long as the icon is tapped.
+ 
+ [Test]
+ Roughly double tap the desktop icon and nothing happens.
+ After applying the fix, double tap can 100% open the app or directory.
+ 
+ [Where problems could occur]
+ If the new code throws any exception, clicking can also be affected.
+ 
+ == Original Bug Report ==
  Double-clicks touchscreen on HiDPI system, sometime it will not be detected.
