> Thanks a lot for producing that doc, it's been very useful.  I think that for now we should restrict this to only default-themed scrollbars and just call into the theme from the thread to raster to scrollbar from the impl thread.

> I've applied this patch locally (on top of https://bugs.webkit.org/show_bug.cgi?id=78028 with a lot of fixups for RefPtr/OwnPtr, etc) and have made pretty good progress on getting things hooked up.  Once I solidify things a bit more I'll provide some more feedback either in terms of a patch or just ideas.  I think we're really close here!

Thanks for the feedback. I just updated the patch based on latest tree and #78028.

The current CCScrollbar implementation just copies everything from Scrollbar. So far so good it looks.

Now I think I have to add some tests for this thing...
