Arduboy on Uno and I2c OLED

When I upload the code for a game to my arduboy uno with I2c 4 pin display the top 3rd of the screen flashes around while the bottom 2thirds has lines through it. The oled is fine for other things. I programed it with a game called space trash which is not an arduboy game. Any thoughts could use some help pls. How do I change the Display type? This is my display U8G2_SH1106_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE)
