[Bug 1292403] [NEW] Suspend to RAM on notebook, wake up with two screens -> solid pitch black shadows

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

After waking from suspend to RAM all shadows are solid black.

I am not sure if this is the cause, but this is how I can reproduce it:
- I suspend my notebook with no monitors attached
- I wake it up with two external monitors attached
-> pitch black shadows

Restarting unity solves the problem.
