I use optifine but with the mod or without the mod these problems continue to arise
 
The first bug that happens is in the tab.When placing a color on the players, the life bar is colored a different color. Example: Players have an orange color to their name. In the tab life bar, the hearts will be shown in an orange color instead of the default heart.This bug happens with all colors (green + red = reddish green)
 
The second bug happens with the advances (Achievements) of the game.The background of the tabs do not appear, instead a black background is placed.
