Visibility config doesn't get rendered if visibility and default store types are different about helm-charts

You might be right. I don't understand some helm constructs, yet.
https://github.com/temporalio/helm-charts/blob/master/charts/temporal/templates/server-configmap.yaml#L60

    persistence:
      defaultStore: {{ $.Values.server.config.persistence.defaultStore }}
    {{- if or $.Values.elasticsearch.enabled $.Values.elasticsearch.external }}
      visibilityStore: es-visibility
    {{- else }}
      visibilityStore: visibility
    {{- end }}
    ...
      datastores:
        ...
        visibility:
          {{- if eq (include "temporal.persistence.driver" (list $ "default")) "sql" }}

includes temporal.persistence.driver, which is defined here:
https://github.com/temporalio/helm-charts/blob/master/charts/temporal/templates/_helpers.tpl#L144-L159
like this:

{{- define "temporal.persistence.driver" -}}
    {{- $global := index . 0 -}}
    {{- $store := index . 1 -}} 
    {{- $storeConfig := index $global.Values.server.config.persistence $store -}}
    {{- if $storeConfig.driver -}}
        {{- $storeConfig.driver -}}
    {{- else if $global.Values.cassandra.enabled -}}
        {{- print "cassandra" -}}
    {{- else if $global.Values.mysql.enabled -}}
        {{- print "sql" -}}
    {{- else if $global.Values.postgresql.enabled -}}
        {{- print "sql" -}}
    {{- else -}}
        {{- required (printf "Please specify persistence driver for %s store" $store) $storeConfig.driver -}}
    {{- end -}}
{{- end -}}

what does {{- $store := index . 1 -}} get resolved into?
still, it looks like temporal.persistence.driver is wrongly introduced key: there is no driver for 'persistence', there are only drivers for some stores, and since temporal basically has 3 possible stores (default + visibility, visibility-es)) - it should've instead been 3 different keys:
temporal.persistence.default.driver
temporal.persistence.visibility.driver
temporal.persistence.visibility_es.driver (I guess - is forbidden in the key paths)

Isn't that because you didn't set up visibilityStore (under persistence)?

That shouldn't be the case afaik. Please correct me if I'm wrong.

It defaults to "visibility" from my understanding of the template.
