Minecraft Win 10 Taking too much RAM

Maybe it's linked to another bug, that is that the screen keeps being red, but this bug is that like every second, Minecraft take another 0.1Mo of RAM, and I kept minecraft opened, and after 1-2-3 days, it is taking 22Go of RAM. That is a real big problem if it's not linked to the other bug. I didn't take any image of that, because my PC was really laggy about this.
Sry for the possible bad english.
