When multiple notification messages appear at the same time and you try to scroll through the messages every second messages is skipped. I´d assume it´s because the notification obeys the "every tick on the mouse wheel forwards 3 lines" rule. This should be changed to every tick on the scroll wheel is one message! Btw I really like the new message style since KDE 4.10, smooth and tidy! Great work!
does it happen with both a mouse and a laptop touchpad?
Can´t help you there, I´m sorry, but I don´t have a laptop with KDE, only a desktop computer.
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug is already resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
