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

[Gunnar Hjalmarsson]

Ok, I have now sync'ed gnome-shell-extension-desktop-icons from Debian
experimental to impish and uploaded new versions of the package to
hirsute and focal. Once the latter have been approved by the SRU team,
it's time to verify all the -proposed packages.

** Changed in: gnome-shell-extension-desktop-icons (Ubuntu Impish)
       Status: In Progress => Fix Committed

** Tags added: block-proposed

Bug description:
  == 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.
  [racb] Since single click code is also being adjusted, please also test that single clicking behaviour has not changed.
  [racb] Since clicking with modifiers (holding Shift and/or Ctrl) is also being adjusted, please also test that modifier clicking behaviour has not changed.

  [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.
