--- Comment #32 from Matheus matheus.venturini@acad.ufsm.br --- This still happens in 8.5. Like previously mentioned, sometimes the entire screen becomes black with only the 3DMark splash screen visible (see attachment 74324), and sometimes only the "dropshadow" bug that was originally described by zil occurs. It seems to be random.
