# 2-6 are gradually slower but safer (6 is still faster than 0).

Por algum motivo, deve ser causado por algo na configuração acima, quando uma janela é feita em tela cheia, aleatoriamente a tela irá congelar, mas o computador funciona bem: o som ainda funciona, atalhos de teclado funciona, eu posso sair com o meu atalho E isso acontece aleatoriamente, ou seja, não toda vez que uma janela é feita em tela cheia, mas isso acontece principalmente para o navegador cromo e MPV, principalmente durante a reprodução de vídeos (embora não no youtube).
Como posso me livrar do problema?
