Hi,

Is there anything I can do to help get this moving forward again?

As mentioned before, I agree the proposed fix might be simply be addressing the symptoms rather than the root cause and I'm willing to keep working on it but I'd really appreciate a second opinion and some insights as to where to direct my attention if this fix proves to be not enough.

For what it's worth, I've been living with this fix on my dev machine for a while now, and it does provide the expected relief to the underlying issue, without me noticing any obvious regressions, neither visually nor performance-wise (I haven't run any targeted benchmarks, though).

With JDK-8199592 fixed, I think it'd be great if we could tackle all of the scaling issues in 16 (might be getting a bit late now, though)
