Bad looking box-shadow

[kasper93]

Hi,

I noticed that top sites on about:newtab page have bad looking box border/shadow. Rounded corners look bad, but also straight lines are blurred and if you look closely top line is thinner than bottom line. Screenshot taken from Firefox build 20180405153002 with dark theme selected.

I've noticed some that might be similar (I can't really tell from the screenshots) and filed https://bugzilla.mozilla.org/show_bug.cgi?id=1452351

I can't reproduce these MacOS reports on my Debian:

I can't reproduce, so I believe this was fixed. Closing. Please feel free to reopen if you still see this issue!
