A diagonal screen tearing appeared after updating xorg-server to 1.20.0. I'm using xfwm4 from git which supports libxpresent vblank method. This bug doesn't appear with glx vblank method.
I tried to bisect the bug and found that it was caused by aab5c46c commit which alters glamor/glamor_egl.c, so I'm reporting to this component.
I reverted the commit (patch attached) and tearing was gone.
