Just wanted to share a quick tip for those who use Awesome (a tiling window manager for Linux/Xorg). To avoid issues with floating windows like dialogs, modals, etc, add the following settings in your rc.lua in the awful.rules.rules section:
{ rule = { class = "Renoise" },
properties = { titlebars_enabled = false,
placement = awful.placement.no_offscreen
}
},
{ rule = { class = "Renoise Plugin Server" },
properties = { titlebars_enabled = true }
},
