When I do an action like advancing with my "Z" key, it sometimes continues to advance for 1 to 10 seconds without me pressing the key and the actions I want to do such as opening a trunk, escape key, are done after the bug and during all this action, I have no control, as if it were a delayed effect. I tried to uninstall / reinstall 64-bit java but the problem still present, for 32-bit java, I had out of memory. (I am in 1.12.2)

PS: i have this problem since long time

Thanks you for your help and sorry for disturbing
