Bug Description

(initially reported at https://discourse.ubuntu.com/t/call-for-testing-chromium-browser-deb-to-snap-transition/11179/85)

When changing the cursor theme with gnome-tweaks, I can observe that some themes aren't respected in the chromium snap. This appears to be specific to chromium, other snaps like evince or gimp use the correct cursors.

Yaru and Adwaita are fine, but Redglass or Whiteglass aren't.

Possibly relevant code in chromium: ui/base/cursor/cursor_loader_x11.cc

Broken on KDE by default.

The KDE theme isn't supported because gtk-common-themes doesn't include the default KDE cursor theme. This MR fixes that: https://gitlab.gnome.org/Community/Ubuntu/gtk-common-themes/merge_requests/17

Fixed for me (Kubuntu 19.10 default mouse theme) as is https://bugs.launchpad.net/bugs/1833611 ("[snap] mouse pointer on Ubuntu flavours is retro-looking when hovering over links").

Confirm, this and #1833611 are both fixed for me (Kubuntu 19.10, Breeze)

Basically, we were referencing a theme that no longer exists, "Human", so the theme was falling back on Default. There is no default theme in gtk-common-themes, so the fallback X11 theme was used instead.
