Classification:Crash/Hang/Data Loss
    Reproducible:Sometimes



 
Summary:
Summary:
Ever since High Sierra, now on High Sierra 10.13.1 beta 3, I am having immense trouble with retina MacBookPro 15" early 2014 2.8Ghz. Several times a day, but often in conjunction with slightly more graphics intense tasks (Photos, Apple Motion, Xcode+Simulator, External Screen), the WindowServer (?) hangs increasingly until not usable any more. 

I identified following workarounds, that temporarily mitigate the issue, but sometimes only minutes later it starts again:
- detaching or re-attaching external screen
- changing screen resolution
- force quitting window server
- restarting the machine

In the following scenarios I also had visual corruption:
- using Apple Motion
- using apple TV as Airplay Display
- using Xcode

This is critical, I cannot work like this, what should I do?


Steps to Reproduce:
- Work with your mac as always, or
- Start and close apple motion a few times, or
- Browse through large Photos in Photos.app



Expected Results:
Nothing should ever hang, Graphics should not be corrupted.

Actual Results:
At some point, It might start hanging, mouse mostly still moving, sometimes loses frames too. 

Version:
10.13.1 Beta (17B42a)

Notes:
To me this looks like some memory leak in the metal/graphics drivers
I have the impression that 10.13.1 beta 2 was better than 10.13.0 and 10.13.1 beta 3, but not entirely sure.
