Description Antti Savolainen 2025-02-20 11:15:06 UTC

SUMMARY
Demonstrative video: https://youtu.be/seWvwn6RS60
If I use a trackpad on my a Thinkpad T470s laptop to zoom, it is way too aggressive. In the demonstrative video I try to use as minimal movements as possible at first and the screen almost instantly jerks to full zoom.

STEPS TO REPRODUCE
1. Use a Super+Shift+Trackpad to zoom

OBSERVED RESULT
The zoom speed is way too aggressive

EXPECTED RESULT
The zoom speed should be so that from top to bottom of the trackpad should be full zoom

SOFTWARE/OS VERSIONS
Linux: Arch Linux
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.11.0
Qt Version: 6.9.0

Tested with a Firefox window on two different systems with trackpads - 6.3.1 and git-master
I was using Ctrl+two finger pinch
I can confirm that on both systems, the zoom is overly sensitive.

I'm not able to get zooming working on the desktop with the touchpad.

My bad, I gave wrong information. The hotkeys for zoom is Ctrl+Super+trackpad scroll
