In recent 1.16 snapshots, in the debug screen (accessed by pressing F3) there is a space missing between the name of the current graphics mode and the previous word.
For example, with fancy graphics and vsync enabled, it says: "vsyncfancy fancy-clouds".
In previous releases of Minecraft: Java Edition it says: "vsync fancy-clouds" because the graphics mode does not appear in the debug screen.
