With PowerPoint 2016, charts appear slowly when switching slides

Problem

When I switch to a slide that contains many charts, the charts first show as gray preview images before they appear one by one.

Gray placeholder while chart is loading

The issue does not occur with PowerPoint 2013 and earlier versions. With PowerPoint 2016, the issue only occurs in Normal view. The Slide Show view is unaffected.

Cause

The behavior can be reproduced with plain PowerPoint charts inserted from PowerPoint → InsertIllustrationsChart. Microsoft informed us that this is a known issue in PowerPoint 2016 and they are working on improving the chart rendering performance.

With think-cell charts, the issue occurs with PowerPoint 2016 and think-cell 9 because the latter uses PowerPoint's native chart component to render charts, instead of the legacy Microsoft Graph component used by previous think-cell versions. We filed a case with Microsoft. If your company has a Microsoft Office Support contract and you want to contact Microsoft to ask for a fix, you may refer to Microsoft case number 117110917129807.
