I just installed 0ad 23 Ken Wood, I don't know what happened but i am getting a warning and an error at the start of a game, when it finished loading my graphics are all kind of weird, sometimes very blocky, other times no shadows and sometimes black buildings and no shadows... I have a picture of the error and how the graphics look attached   resume of pc Specs: i5 6500 16 Gb ddr4 ram 980ti GPU
