*** This bug is a security vulnerability ***
Public security bug reported:
I have noticed strange issue, since i updated my kubuntu from 14.10 to 15.04.
So the system suspend works fine, but from time to time when i wake my PC up
from this mode, I see only some weird triangles, chaotically moving on a
screen. It looks like on the picture i taken.
What i see in logs is:

This error is instantly repeating.
Sometimes, after few seconds, this issue just dissapears, sometimes reboot is
necessary.
I use nvidia as a primary display:
i nvidia-346
- NVIDIA binary driver - version 346.59
I have 2 external screens attached (1 connected to HDMI, second to
display port), laptop's screen is not used.
