SUMMARY Sometimes when I work with an application (say Sublime Text) and I use mouse wheel to scroll the content, notification appears and mouse wheen no longer scrolls the content. As soon as notification disappears, I can scroll with mouse wheel again. STEPS TO REPRODUCE 1. Start Sublime Text (or Firefox) 2. Scroll with mouse wheel 3. Let any notification appear OBSERVED RESULT Content doesn't scroll when notification is displayed. EXPECTED RESULT You can scroll as usual. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Neon 5.16 (available in About System) KDE Plasma Version: 5.16.5 KDE Frameworks Version: 5.62.0 Qt Version: 5.12.3 ADDITIONAL INFORMATION I doesn't happen every time.
