Worsened interface and graphics, [GAMEPLAY]

• After launching a game, the UHD become very pixelated and blurry, exp bar allways full making me unable to see my exp.

• Creeps and Monsters lifebars become transparent and make last hitting harder than usual.

• Every champion's manabar shine like if manaband was up.

It happen approximately one game out of 10 and often in a row.

After research, I heard it was caused by tabbing out during loading, but since I allways tab out during loading screen and it's not doing it every game, I don't think this is the reason.

Thanks for responding.

EDIT : Will bump or redo this post with screenshots if it happen again.
