A new xorg version has been installed yesterday 14.02.2018. I could make a video of the problem on my screen before that installation, and have joined it. The bug as posted is still active with the new version. It is not easy to reproduce. Sometimes it comes often, sometimes not. Open and close several windows, switch between tasks..., or verify source code. So long I remember, this bug appeared before september 2017. No problem in year 2016. On the video one can see that abnormal blinking stops on next going into sleep state.

Conditions: - in the upper bar the display of the seconds must be enabled (in my case the entire date-and-time is displayed, excepted the week number); - system has set himself automatically in sleep state after the selected delay (in my case the option "lock the keyboard" is not enabled). On awakening, for example by using the shift touch, parts of the screen are blinking according to 1 second rate and 3 seconds cycle. Coming back to normal behavior needs to close and re-open windows (no!, not M$), etc... To help to reproduce: - edit a message with thunderbird; - select ubuntu "parameters"; - select "Luminosité & verrouillage" ("Brightness & keyboard locking"?); - select "1 minute"; - wait 1 minute and going into sleep state; - when in sleep state press the "shift" key; and then I have a blinking "Christmas tree", too complicated to be described. I tested it again 3 times why writing this post (firefox had also an opened window, under thunderbird; with firefox alone, the screen blinks only one time -should also not-). When the seconds are not displayed in the upper bar there is no problem. Please do not blame me if xorg is not involved. A way to post had to be found.
