SUMMARY I am using Linux Mint 22 with an E-Yooso mouse wired via USB to my HP Omen laptop. STEPS TO REPRODUCE 1. No specific way to reproduce this. OBSERVED RESULT Various times I will notice the the scroll wheel does not scroll the Okular window. This is intermittent. I never notice this happening in my other Mint apps. Usually, this happens just after returning to the Okular window. If I continue to scroll the wheel eventually it will work. Most of the time I resort to the keyboard up/down keys as they consistently work. EXPECTED RESULT Consistent scrolling. SOFTWARE/OS VERSIONS (available in the Info Center app, or by running `kinfo` in a terminal window) 'kinfo' is not available and Mint System Info shows none of this info. Linux/KDE Plasma: KDE Plasma Version: kde-plasma-desktop/noble 5:146ubuntu3 amd64 KDE Frameworks Version: kde-baseapps/noble 4:23.08.5+5.146ubuntu3 amd64 Qt Version: both QT5 and QT6 are installed.
