Description Mike Bluett 2024-11-09 20:09:17 UTC

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.

Hi! Would it be possible for you to please provide a screen recording of this issue, so that folks could see the surrounding circumstances when this bug shows up?

Also, could you please mention which method you used to install Okular 24.08.3 on Mint - Flatpak, compiled from source, backports/PPA, or otherwise?

Thanks!

It appears this problem was recently resolved as the later version 24.12.1 I am running now no longer has the problem.

I noticed in the release notes that there had been some fixes that seem relative.

Awesome, glad it's working for you now!
