I seem to be experiancing rendering issues with the last Pwoer BI Report server. As you can see from the attached images the spacing is all over the place with these cards. It also occurs with Tables too
left is the PowerBi App and right is the web site.
I am having a similar issue where Chrome (v45.0.2454.85m - I know its old but solution on locked down on-premise platform) renders PBI Reports in the PBIRS Web Portal in the wrong position effectively displaying only the bottom half of the report. Looking into the Chrome Developer Tools shows that "div.displayArea" has a style setting which, in the March 2018 upgrade, is set to "position: absolute" whereas in the August 2018 upgrade this is set to "position: relative". Changing this back to "absolute" seems to fix the issue in Chrome. Obviously this "fix" is not permanant and wondered if it can be implemented on the server side as a quick fix?
Reports render fine in IE (11.0.9600...) which doesnt seem to react to changes to the same position style setting.
