@Peti - You say "I have tried almost all suggestions and drivers", so I assume that you have tried running "sudo nvidia-xconfig --composite" and then rebooting.
Please open a new bug report by using the ubuntu-bug tool and attach the output of unity_support_test -p
You can link to the new bug report here if you like.
