If you enable mouse wheel zoom in Gwenview options page then moving the wheel up will zoom in and moving it down will zoom out which is the natural behavior, but if you hover over zoom combobox at right bottom and use mouse wheel the behavior becomes the total opposite : moving the wheel up will zoom out while moving down will zoom in.
Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0?

Can we ask you to please check if this is still an issue with Gwenview > 25.08.0? Thanks, it's still repro in Gwenview 25.08.0, the list of zoom values should be reversed in that combobox.
The issue is the following: The zoom slider works as expected. But if you hover over the dropdown menu, scrolling navigates in this menu. Now the options are listed in such a way that the behaviour is reversed. Easiest solution: Reverse the order of the options in the dropdown. This would also increase usability.
The relevant code lives here I think: https://invent.kde.org/graphics/gwenview/-/tree/master/lib/zoomcombobox
