alright 1st check up with your graphics drivers
here. Sony eSupport - Electronics - Select Your Model
enter ur model and make. Find the radeon graphics driver
, download it and install.
If that does not seem to work, try this Update graphics drivers:
AMD :AMD Driver Autodetect
As well mine-craft runs through java i believe, as i doubt java would be the problem. Optionally you can try to update that.
This seems to be a minor display driver problem. Please report back if any solutions are found, or if my steps did not take care of your problem. Thanks
