Hello, A bit more of information:
- The issue happens using X or in a plain terminal, although in the terminal the situation is worse, the image dissapears more frequently. - The issue is still happening with SID's kernel 4.4 - I observe once in a while the following messages at the bottom of my dmesg: [ 23.189247] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A [ 23.242982] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder B [ 23.243002] [drm:cpt_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun Best regards.
