This looks like a PrimeFaces bug, but you can work around it by hiding tooltips on pagination events via JS.

<p:dataTable value="#{bean.val}" var="row" rowIndexVar="rowIndex" rows="10" paginator="true">
    <p:ajax event="page" oncomplete="hideTooltips();" />

    <p:column>
        <h:outputText id="text" value="#{row}" />
        <!--
            since p:tooltip is located inside an iterative component (p:dataTable), we can't
            just define a static widgetVar value, because there will be a widget instance for
            each iteration, and each instance must have a unique widgetVar value, so we'll
            use rowIndex to achieve that
        -->
        <p:tooltip widgetVar="textTipVar#{rowIndex}" for="text" value="Tip" />
    </p:column>
</p:dataTable>
<script>
    function hideTooltips() {
        /*
            we've defined a bunch of widgetVars with a dynamic name, so we'll iterate over
            all widgets on the page and find the ones we need by looking for a known
            widgetVar prefix
        */
        for (var w in PrimeFaces.widgets) {
            if (w.indexOf('textTipVar') === 0) {
                PrimeFaces.widgets[w]._hide();
            }
        }
    }
</script>

This uses an undocumented Tooltip widget method _hide, keep that in mind when updating to another PrimeFaces version, e.g. the method's name could change. The PrimeFaces.widgets object is undocumented too.

Incase anybody else struggles with this, I think I found a solution worth trying. In my case, I had a tool tip that showed when I hovered over a commandButton but if I clicked it it would run an ajax request and return, update a component and finish but the tooltip would still remain. This is what I did to fix it.

<p:tooltip id="saveDeleteTooltip" globalSelector="[data-tooltip]" position="top" hideEvent="mouseleave click"/>

Supply two events for the hideEvent attribute and seems to recognize and use both. The first is for normal mouseout but the second does fire when I click on my commandButtons it does hide the tooltip like it was supposed to do.
