D17884: [effects] Enable touchpoints by default

ngraham added a comment.


  In principle this might be acceptable, but I'd like to make sure we don't regress anything like we did with the Screen Edge effect when that got turned on by default for all users (not just those with touch hardware): https://bugs.kde.org/show_bug.cgi?id=387775
  
  I'd like to try it out, but the effect does not seem to have any effect on my system (a 2-in-1 convertible). Is this a known issue?
