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.
