--- Comment #39 from zyf0330 <zyf034...@gmail.com> --- Another related thing is, after change compositor settings (when use OpenGL 3.1 or OpenGL 2.0) and apply, the whole screen is lag, except I use Xrender. My previous computer has no this problem, current computer is too old which is MSI GE60 2PG. So Maybe it is a hardware compatibility problem. -- You are receiving this mail because: You are watching all bug changes.
