I update to stable version of 2026-07-23 so from plasma 6.6 > 6.7
It appears somehow that I have some zoom in.
I have no mouse, but a touchpad.
Googling from another PC some says that the solution is:
REF: https://unix.stackexchange.com/questions/806756/how-do-i-zoom-out-my-whole-desktop-on-kde-linux
Try these keyboard shortcuts:
Meta (Windows key) + -: Zoom out
Meta (Windows key) + 0: Reset the zoom to normal (100%)
Meta (Windows key) + + (or =): Zoom in
These keyboard shortcut have no effect on my laptop.
It’s not described by others, but me since I’m in this “zoom mode”, it’s eating a lot of ressource and it even crashed Chromium.
Thanks.
