Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.3.0-2-default x86_64
Distribution: "openSUSE Tumbleweed (20151209) (x86_64)"

-- Information about the crash:
I am using SuSE Tumbleweed, I tend to be updated at all times, I am experiencing serious regressions regarding DisplayPort under Plasma, though this problem might be in the intel display driver.

My computer is an Intel NUC D54250WYK

If there's been a long delay since the last time I used my computer, the screen remains off for say 3-4 minutes, then the PC comes back to life and is fully operational. I will enable SSH to try to workaround this by triggering some xrandr with the hope that I can resume my session faster.

Thank you all for pushing opensource computing KDE to unmatchable levels of awesomness!!!

The crash can be reproduced every time.
