In libreoffice does not work after clic in save a document (Without libreoffice-kde5 installed, because is ugly in dialogs windows and tabbed UI). In Evince the problem is variable. STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
This isn't related to the Breeze GTK theme; we don't affect or have any control over the scroll behavior in these apps, and Libreoffice with the KDE VCL installed does not use the Breeze GTK theme. I would recommend that you file bugs on the apps themselves.
