I have two mice: One is wireless, the other USB, both Logitech. Suddenly today, the buttons started deciding on their own what they meant. For example, the left button in the center of a Firefox tab closed the tab instead of "topping" it. The scroll wheel magnifies or shrinks instead of scrolling. Then if I use the other mouse, the correct behavior is restored.
This is entirely new — never happened before today. I thought this was only a Firefox thing so I restarted it, but that didn't help. Then I reinstalled it, and that didn't help. I cleared all my history and caches and that didn't help. Then I noticed it in Okular and Evolution. I haven't rebooted. I'm using Debian 12 Bookworm. My kernel is 6.1.0-34-amd64. Is this a Debian thing, or a KDE thing, or a Wayland vs X thing? I don't know how to tell whether I'm using Wayland or X at the moment.
