Matcha-sea Matcha-sea-grab Introduction Often asked in the Manjaro forum and eg. answered in this thread. The simple workaround is to use some keyboard shortcuts: [alt]+[f8] and just drag the mouse. [alt]+[rmb]+[drag]. changes either width or height depending on drag direction There’s a third answer in the post telling gtk.css css to increase border and/or gripper (may be affected by CSD (client side decoration)). So I wonder how to adjust that to get a better handling of the standard mouse operations grab and drag borders.
