The cursor flashes both when connecting the screen via VGA and HDMI. When the screen is connected directly to the VGA or HDMI ports on laptop, the flashing does not occur. Similarly, the cursor never flashes on the second screen. The system is Ubuntu 16.04 LTS on Dell Latitude E5470 with integrated Intel graphic card.
