The visible effect in the video is similar to what I see on the LVDS display. I also see some influence of the mouse pointer position on the blanked areas. The effect on the external screen is more like single scan lines jumping to the right and back, at a high (but still visible) frequency. What I'm missing in the report, are some log entries I'm seeing on my notebook: Apr 30 08:50:23 localhost kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun Apr 30 08:50:23 localhost kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun Apr 30 08:50:29 localhost kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Apr 30 08:50:29 localhost kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun Jan
