Hi, I also get screen artifacts with the new -4 and -5 kernels: - display going on/off/on regularly, usually on first key press after switching between different screens in a multi-display setup - current window briefly flickering, usually on first key press after switching between different screens in a multi-display setup - main display's left origin briefly shifted to the right causing a "wrapping" effect
I didn't experience a system crash though. Cheers! Sylvain
