Computador portátil. GPU: AMD Radeon 780M integrado, sistema operacional: Arch Linux, WM: Hyprland v0.39.1 (wayland). Aconteceu também no Linux Mint 21.3 com Cinnamon (X11), então parece que não é distribuição ou WM.
Às vezes, quando ligo a tela (integrada) depois que ela é desligada (economia de energia, mas não suspensão, hibernação, etc.), a tela fica toda branca. Toda vez que isso acontece, recebo esse erro.
