Disable the Xfce compositor, vsync feature in that causes it tainted. That might not help. Use the display port, development focus is in the display port. Developers have display monitors and are not interested about hdmi so much.
That's it, I disabled V-Sync on Xfce compositor settings and there are no more freezes or errors. So this is a Xfwm4 bug?
