I want to share my experiences - I have not searched for an issue. Same issue here - but not limited to terminal - occurs also in Graphical mode (KDE). When the screen flickers it flickers both in GUI and terminal.
The flickering is fast moving left and right. Sometimes the top ~1/5 of the display is displayed in the bottom. I am not sure if the flickering is triggered by toggling windows (Alt-TAB) or it just occurs randomly. Closing the lid (suspend) and opening the lid again makes the machine usable again. I am using kernel 4.9.0-4 on a Lenovo E550: 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09) CPU: Intel Core i5-5200U I have not tried using reverting to kernel 4.8.0-3 but the timing of the issue matches well.
