It sounds like you're seeing a variety of issues with your retina MacBook Pro when waking it from sleep. The following Knowledge Base article offers up some great pointers for troubleshooting:
OS X: When your Mac doesn't sleep or wake - Apple Support
If your Mac doesn't wake when you expect
Your Mac might pause a few seconds before it wakes up. If it doesn't seem to wake at all, check for these possibilities:
- Your screen brightness might be turned down.
- If you're using an external display, your display might be turned off.
- Your Mac might be in safe sleep. To wake from safe sleep, press the power button.
- Check for a sleep indicator light, if applicable, and make sure that your Mac isn't turned off.
If the previous steps don't work
These additional steps may help identify or resolve the issue:
- Reset the SMC.
- Reset NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
- Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
- Try to isolate the issue by using another user account.
Thanks for reaching out to Apple Support Communities.
Cheers.

Nov 11, 2015 2:27 AMby Vipers07,i' ve now see that if i close the lid and then open the lid all is working ok.
if i let the laptop with lid opened for a few hours, the login screen freezes. i than close the lid and let it for a few hours and then when i open the lid the login screen functions ok ...
I think that when lid is close the laptop probably hibernates and whend is lid opened it goes to sleep.
The sleep seems to be makeing the problems so i need to solve this.
How can i stop the automated sleep ?
Apple needs to find a solution and came with a patch/update for this issue about the sleep process and the relating problems...

Thanks for the follow up on what you've tried in regards to your MacBook's sleep issue. If the isolation steps recommended in the previously reference Knowledge Base article did not help then due to the nature of your question, it may be best if we get you in contact with someone who can look into this further.
