Did the "Background contrast" desktop effect get turned off?

No. It's still enabled.

Got another report of this too. Confirming.

Maybe a change in plasma-framework or KWindowSystem?
Comment 6 David Edmundson 2019-09-17 15:49:50 UTC
I helped debug someone with this at Akademy, he didn't have kwayland-integration compiled and installed
Comment 7 Patrick Silva 2019-09-17 16:35:31 UTC
kwayland-integration package is already installed on my Arch Linux.
Comment 8 Alberto Díaz López 2019-09-17 21:53:48 UTC
Same issue here, just after updating to KDE Frameworks 5.62.

Appreciated that 'only' happens when the background color is a light one, i just checked but i detected other behavior, the issue seems to appear when the window under the panel/widget isn't a KDE one, checked with Qtransmission, blur confirmed, checked with Firefox Developer Edition, blur confirmed, checked with Dolphin, blur doesn't appear, checked with Telegram Desktop, blur confirmed, checked with VLC, blur confirmed.

So it has to be something about the non-KDE Software.
