When you press ‘specate’ (for gold rush, for example), the canvas width is set to browser width and can’t be reduced. This means that on widescreens vertical scrolling is always needed. This is especially annoying because playback controls are at the bottom and info like collected gold amount are at the top. Sometimes level width is more than canvas width, so it can be scrolled inside a canvas horizontally(together with vertical scrolling in a browser). When i resize the window, it adjust the height of the canvas, but there’s a lot of unused space under the playback bar, and canvas does not take 100% width, but its content still can be scrolled. All this happens with page scaling=100% so scaling is not the cause.
