Yes, I am concerned about memory uses in nightly builds, as that's behaving differently then STP and Safari (macOS Sonoma only), where STP and Safari seams handling memory allocations in WebContent process, so memory uses in GPU process is normal, and WebContent process releases memory back when needed. 

But when using nightly builds, GPU process seams handles memory allocations for dom rendering, so this causes higher memory uses in GPU process, and it doesn't release allocated memory back and causes leaks. You can see the difference in screenshot attached here https://bug-269302-attachments.webkit.org/attachment.cgi?id=469873 (not sure if the issue is ARM CPU specific)

I can share more information if needed.
