My recent weird "bug" was when I installed a new Linux distro, just last week, to get away from weird graphical issues with KDE (switched to PopOS for hardware support). On boot, my mouse started moving really erratically. I would try to move it and it would just jump all around the screen, but only with Razor mouse, not my logitech one. Great, I think, I traded display issues for mouse driver issues. But it was weird, because it was fine during the live USB. I spent a bit of time debugging inputs etc, maybe it's a weird driver issue. I suddenly remembered in my HS days when the school ordered new mousepads which had bright yellow lines on them from some logo, making them incompatible with the "new" laser mice. It was some cat hair on the sensor :D
