I am pretty sure, that apple also has something to do with this issue, cause this error only happens since macOS 10.14.5
If you downgrading to 10.14.4, this issue is not appearing ... no matter which version of ESO.
I tested it again by downgrading my iMac to 10.14.4 and everything is ok ...
As I read -> with macOS 10.14.5 apple did change something within their metal drivers ... thing.
So the error also might appearing caused by that.
