SUMMARY Un-zooming using Ctrl + mouse scroll seems to go the opposite way. Once zoomed in and out, it seems to behave afterwards. STEPS TO REPRODUCE 1. Open dolphin and set view to details mode 2. Now hold down Control key and scroll down to zoom out OBSERVED RESULT Rather than zooming out it zooms in. If you choose to zoom in by scrolling up, in step 2, then the zooming out actually zooms in even more. Something spooky going on! EXPECTED RESULT Zoom the right way, in or out. SOFTWARE/OS VERSIONS Windows: N/A macOS: N/A Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.105.0 Qt Version: 5.15.9 ADDITIONAL INFORMATION
Can also confirm on Arch 5.27.4 After pressing ctrl twice it works normally again (press ctrl -> release ctrl -> press ctrl+mwheel).
Can confirm, Ctrl + Scroll does funky things in Dolphin. For me, it appears that it only zooms one way, no matter if you scroll up or down on the mouse wheel. I'll try the pressing ctrl twice trick. I have multiple panels open in Dolphin, and like Icon View with splits, and I zoom in and out often, and so this bug is a little annoying.

Do you use a mouse or a touchpad ? I would guess a mouse ?
Ah, yes, the details. I am using a mouse, and it's under Wayland which does change the driver a little.
Holding down Alt and scroll wheel moves the icons left and right as expected.
More testing. The problem shows the same in X11 and Wayland, and on every view type in Dolphin, eg List, Icons and Details. When you zoom in so much that it don't fit on one screen anymore then the holding down of Alt and doing the mouse scroll wheel thing works as expected. The system is a fully updated Arch with KDE desktop. I usually run Wayland, but just for today I ran X11 to see if this bug is visible there too.

(In reply to Evert Vorster from comment #10) > It seems that there has been a regression, and this bug is alive again. > > My system info: > Operating System: Arch Linux Please note the "Version Fixed In" Field says 23.12. Which means it is fixed in Dolphin version 23.12. or later. Arch stable is currently on 23.08.5-1, so that's why you don't have the fix.
