Im using a bit of a datted system, "single core original socket a amd sempron overclocked to 2.8" with a rather legacy video card. With the new version of mint when I install the graphics are "pixelated" AND theres a clear box around my cursor, this appears even in compatibility mode on the live cd and after boot, any suggestions would help.
AS I stated below on how to fix my xorg which fixed my graphics, to fix my video i entered vlc, settings, then prefrences, then click advanced options video output model, change from default to x11 video output and problem solved!!!
hope I help some other people.
