Pierre Wilch, given this issue only happens when using Unity, I'll
reassign to Unity so a specialist may review.
** Description changed:
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 is set to automatically go into 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.
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-).
WORKAROUND: When the seconds are not displayed in the upper bar there is
no problem.
+
+ WORKAROUND: Use GNOME Flashback (Metacity) session.
