SUMMARY When you open a dialog near the panel (e.g.: kickoff), the part of the dialog that's near the panel is unnaturally more white. STEPS TO REPRODUCE 1. Take a transparent desktop theme to see this better 2. Press the meta key to activate kickoff OBSERVED RESULT The part of kickoff (or any other dialog) that's closer to the panel is more white. EXPECTED RESULT Kickoff is uniformly blurred. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.17.80 (master) KDE Plasma Version: 5.17.80 (master) KDE Frameworks Version: 5.66.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION See bottom of kickoff in this screenshot for reference: https://phabricator.kde.org/file/data/fbfelsfbxqsdzrjob6e2/PHID-FILE-4xtz5oo7zfh4q7trwucb/Screenshot_20191128_153515.png
In more technical terms, I think the request here is for the blur effect to ignore the impact of any panels when it's applied to something that uses the Sliding Popups effect.
