I did a build and install this morning, a bunch of quic-related changes in that.  Now everything seems to be working on my paste site.  Large pastes work, and I can reload the page a ton of times without it hanging until browser restart.

I have found that the roundcube package doesn't work completely right with quic/http3. It has proven to be an excellent way of revealing problems.  The roundcube package is a php webmail app that utilizes a database and an imap server.  It's using many of the features that are possible with modern browsers.

When I first started this http3 journey, I couldn't even log in to roundcube because any POST request was failing ... but that problem got fixed.  Now I find that when quickly jumping between folders in my big mailbox, the site stops responding.  If I switch back to http/2, everything works.  If it would help, I can give one of the devs full access to use my roundcube install and experiment with the config, see if maybe I am doing something wrong.

Here's my haproxy -vv output.  I built it from the master branch right after I saw the dev12 release announcement:
