problems with cobblestone

Unable to reproduce. Also it looks as though you're using a resource pack. Do you have the same problem when all resource packs are disabled?

yes I do have the same problems without the ressource packs. The ressource pack is Faithful for 1.11 by xMrVizzy and Vattic

Outdated and broken graphics driver. Please get an update to version 15.xx.xx.xx from http://downloadcenter.intel.com/ . See also MC-32606

ok

it does not work, there is this error message: "The driver being installed is not validated for this computer. Obtain the appropriate driver from the computer's manufacturer. Setup will exit."

there I updated it

however the problem still occure

I can't confirm it. I tried it in both survival and creative and the cobblestone still as a cobblestone. Are you sure, that there are not ghost blocks or resource pack incompatibility issue ?
