The latest update to KDE Neon made the Status & Notifications panel too transparent. It's hard to read the entries when you have a webpage like http://www.omgubuntu.co.uk/ open under the panel. Please make transparency optional or fine-tune the opacity value for it not to be so transparent. Reproducible: Always Steps to Reproduce: 1. Open a webpage or program with colorful graphics and text, like omgubuntu.co.uk 2. Open Status & Notifications Actual Results: Opacity level is too low, which makes it hard to use the panel. Expected Results: Panel shouldn't be transparent.

Note: I use the Breeze Dark theme.
Looks like background contrast effect is not enabled? Or gpu driver update broke it. Please provide the output of qdbus org.kde.KWin /KWin supportInformation
Your first guess was right. The effect was not fully active (see screenshot 2). I unchecked it and checked it again, and now it's fine again. I hadn't touched any graphical settings though. That happened automatically with the lastest updates.
