I tryed to find answer for this, but i did not, but i hope i'm not the first one to notice this..

I have exported about 80 different kind of presentations from PowerPoint 2013, i mainly use newest Firefox 37.0.1.

sometimes when i open the html5 index file i get some slides looking like this:
so the background and image graphics seems to be rendered on the screen incorrect.

When i adjust the Firefox window size away from full screen:
it fixes the background.

When i adjust Firefox window size manually just littlebit
is shows the presentation right:

I have tested also newest Chrome and newest Explorer,
i have not been able to get same error with them.

Please help, how to fix this..
i have quite big portal building going on..

Thank you for posting here!

The thing is that HTML5 content can be displayed differently in desktop browsers due to the format and browser peculiarities.
Here is some info from HTML5test project:

Firefox: ... t.PNG?dl=0
Google Chrome: ... 2.PNG?dl=0

However, I would appreciate if you provide me with the sample-presentation that can help me to explore this in our lab. Please send the file to
Please indicate me as a recipient. Thank you in advance!
