Render resolution exceeds window dimensions on some macOS systems, causing performance issues

When I run the Snapshots for MC Java Edition 1.13 I get a fullscreen resolution of 3360x2100. My Mac has a screen resolution of 2880 x 1800. Because of this, my computer runs very hard when playing the snapshot. Heats up quite quickly (which isn't normal) fans are going like crazy, my FPS drops easily below 50 (Normally get around 60 on 1.12) and the game becomes VERY VERY laggy whenever I place any blocks or break blocks.
