The icon of close button for any dialog in Powerpoint in web version is changed from "X" cross icon to thunder icon.

Your Environment

Expected behavior

When I open any pop up dialog in MS powerpoint then the close button should appear with a 'X' button but instead it is coming with a different icon now.

Current behavior

Open the PowerPoint web version .
Create a new file, Go to Home -> select icon to add a new add-in for PPT -> dialog box opens
Check the close button icon when the new dialog opens, the close button icon 'X' is not there and instead some thunder icon is coming up which is not correct.

Steps to reproduce

1. New File Open in MS PowerPoint
2. Click on Home
3. Select icon to add a new add-in for Powerpoint
4. Click on More Add-ins button.
5. New dialog box appear.
6. Check the close button icon.(It is not coming as 'X' icon instead some thunder icon is appearing.)

I cannot reproduce this issue. I get the "X" as normal. The font in your screenshot isn't the standard Office font, so there's something generally wrong with the rendering of the UI in your dialogs. Do you see this same problem in Excel or Word? Does rebooting the computer fix the problem?

[ankitmahapatra]

I checked with all my colleague as well. All of them face the same issue.
And it is only coming in powerpoint and not in word and excel.
Rebooting also I've tried but its still persist.
