After GNOME 3.32 upgrade, the theme does not cooperate well with dash-to-dock extension. Here's the dock with default theme:

And here it is with Arc theme:

As you see with Arc the icons have strange spacing between them, which is somehow not counted when calculating the size of the dock, thus resulting in some icons appearing only partially or being completely out of visible area. It generally gets worse when you open a lot of applications and then close some of them - the spacing between the icons gets even bigger in that case. There is also some ugly spacing below the icons.

Please let me know whether this is an issue fixable in Arc theme or whether it has to be fixed in dash-to-dock extension. This is probably related to #217

Also seeing issues with dash to dock with the latest gnome shell update (3.32.0+46+gfea019277-1) on Arch. Evidently the changes to dash margins/padding in commit 4802bc1 are messing things up - and are not worth the hassle just to have the running dots visible on hover.
Best solution is to revert the commit I think.

Tested the fix/revert and now the original problem is gone - thanks!
