On Linux Mint if you click Alt + Mouse button, it goes into drag window mode. And yes, I am sure there is a fix for this, I am just too lazy to dive through Linux docs right now. 😅 So it's kinda my fault ... still it'd be nice to have a workaround. Thx!!! (By fix I mean, I am sure there is a setting to disable that in Linux Mint, but I cannot find it right now.)
