--- Comment #13 from Sanjay Kumar <hypertree at yahoo.com> ---
Webkit 7616 1.2.2 was built two weeks ago Feb 17, 2023 and had the bug:
https://github.com/WebKit/WebKit/commits/WebKit-7616.1.2.2

16.4 beta 1 was released: 16th Feb - Thursday and included the bug.

First good build happened just 4 days later - 21st Feb, 2023
https://github.com/WebKit/WebKit/commits/WebKit-7616.1.3

git log --oneline WebKit-7616.1.2.2..WebKit-7616.1.3

Includes 355 commits including two critical ones Kimmo is referring to:

b37b92a67793 Update ANGLE to 2023-02-14 (2bcf94cc0b577225f7b925dd0cd1ed03541e30db) 
https://bugs.webkit.org/show_bug.cgi?id=252237
rdar://problem/105447176

This includes this revert:
ee64836f7 Revert "Metal: Optimized BufferSubData per device"

And this fix:
ab998e353f10 ANGLE Metal program memory cache is unbounded https://bugs.webkit.org/show_bug.cgi?id=251915 
rdar://105174119

Later tags 1.3.1 (Feb 23, 2023) and 1.3.2 (Feb 24, 2024) have just one unrelated fix and re-versioning.

16.4 beta 2 was released: 28th Feb - Tuesday an still has the bug - meaning its not based off of WebKit-7616.1.3.

Which Beta will it include 1.3.x tagged code? Hard to tell.

But I see a March 1 commit (yesterday) to update Safari UA to 16.4:
https://github.com/WebKit/WebKit/commit/3c220716e9d6cba24dc20c174b43aceb94051934

So I suspect 16.4 release will contain the fix - lets hope early as next beta - next week.
