Did some more digging.
The problem is that the fts-solr plugin has a global solr_conn pointer, that persists between users. I think this patch fixes the problem:
--- a/dovecot/fts_solr_plugin/fts-solr-plugin.c
+++ b/dovecot/fts_solr_plugin/fts-solr-plugin.c
@@ -50,6 +50,13 @@ static void fts_solr_mail_user_create(struct mail_user *user, const char *env)
{
struct fts_solr_user *fuser;
+ /** solr URL may be different per-user **/
+ if (solr_conn != NULL) {
+ solr_connection_deinit(solr_conn);
+ solr_conn = NULL;

fuser = p_new(user->pool, struct fts_solr_user, 1);
if (fts_solr_plugin_init_settings(user, &fuser->set, env) < 0) {
/* invalid settings, disabling */
