https://bugs.freedesktop.org/show_bug.cgi?id=89909 --- Comment #4 from Marek Olšák --- Can you still reproduce this with current Mesa git? Anyway, this is a game bug. The game generates NaNs, which produces the artifacts. The game might have been designed for DX9 or GL2 hardware, not GL3. It shouldn't occur anymore, because NaNs are disabled by radeonsi. -- You are receiving this mail because: You are the assignee for the bug.
