2.5b2, 10.11, 2 displaylink devices, resume from screensaver leaves 1 screen blank
 

Hello,

When deactivating the screensaver, at least 1 displaylink monitor remains as a black screen. I have to enabling then disable mirroring to get the display back. This always happens.

Also fresh reboot sometimes results in both displays showing background but not application windows. Again have to enable then disable mirroring (or slightly adjust monitor arrangement) to get applications displayed. This sometimes happens.

Kind regards

I'm seeing similar problems related to ScreenSaver + 10.11 ElCap + 2.5b2. After a fresh reboot things work normally for a while but after some time (not sure what the trigger is) the DisplayLink display will stop "sleeping". The other 2 monitors go to sleep but the display connected to the DL just stays on.
