After a random amount of play everything except solid blocks (placed or generated) starts to flicker, this goes on for a few seconds and it also crashes the GPU so that no programs will work. Forcing me to restart to get rid of the symptoms. Only Minecraft causes this, however I have not tried any other games (as I don't have any installed)
