SUMMARY I recently upgraded from Xubuntu 20.04 to 24.04 and found Okular to be completely useless because scrolling completely overshoots and seemingly no way to disable it. I'm using a laptop, but I'm using a mouse not the trackpad (Logitech Wireless Mouse): ``` lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 046d:c534 Logitech, Inc.

Go to Settings -> Configure Okular 2. Disable smooth scrolling 3. Restart Okular 4. Use the mouse and drag the the PDF OBSERVED RESULT See the video: https://youtu.be/TH0zeToL1T4 The PDF overshot so much the video encoder couldn't keep up. It scrolled 4 pages. Whereas the version bundled with Ubuntu 20.04 would only send me to the end of the 1st page. EXPECTED RESULT Scroll should not have inertia.

I forgot to mention: This is about scrolling using drag with the left click button. 1. Hold left click 2. Move cursor 3. Release left click
