macOS Tahoe fails to close NSWindows after display sleep, causing window accumulation and performance degradation
We have a feedback open for this problem on Tahoe (FB21391882) as well as a DTS track. Our QA team has verified that this is still occurring with the Golden Gate Beta 1.
I am wondering if this is going to be prioritized as an issue in Golden Gate, or if this is not going to be looked into any further.
Honestly I am not sure this is the forum for this, but I was not sure where else to ask at WWDC this year due to the lack of 1-1 appointments.
