When using the webflow it would be nice to set the default "To" address in "Review your patchset".

When working on a project it's quite likely that you are most of the time sending the patchset to upstream. It would be nice to avoid having to find the appropriate mailing list when sending a patchset.

Any reason not to switch depth buffer to 24 bits for now?

64k seems reasonable, 16M less so.

I'm not sure what you mean by that.

Reproducer is here: https://github.com/egonelbre/expgio/blob/master/too-many-rects/main.go

My best guess it's hitting some buffer limit for GPU-s. I haven't done any extensive debugging.
