Title:
panel and visually-corrupt launcher shown on login screen after resume
from suspend
Status in Unity:
New
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
My Macbook Pro 3,1 went to sleep automatically because it ran out of
battery power. When I resumed, the unity launcher was drawn - in a
visually-corrupt state - on the lightdm unlock screen. The top panel
was also visible (see attached screenshot).
The visual corruption in the launcher was identical to the behavior
seen in (and reportedly fixed by) bug 915265. The corruption did not
clear after unlocking the screen.
To reproduce:
1) Configure the system to suspend when power is critically low. The power
settings control panel does not provide this option (another bug?); I have the
gconf-key /apps/gnome-power-manager/actions/critical_battery set to 'suspend'
2) While logged in, exhaust the battery to force the system to automatically
suspend
3) Plug the system into a power source
4) Resume the system
Expected results:
System wakes up and presents the unlock screen. The launcher and panel are
not displayed on this screen
Actual results:
System wakes up and presents the unlock screen. The launcher and panel are
drawn over the unlock screen. The launcher is visually corrupted, probably
because we haven't refreshed the backing FBO after resume.
When the system entered suspend, I did notice that the unlock screen was
drawn onscreen just before the machine went to sleep. I am fairly sure the
launcher was displayed over the unlock screen at this point - so the problem
may have occurred before the machine went to sleep, not afterwards.
