Hey @ehfdub. If you want to link me a github issue I can check it out I'm
@snide on github if you want to ping me there. We do support IE, up to 11, but browser to browser there will always be slight changes, especially with user driven interfaces like Kibana.
To your specific reference I assume you're talking about a dashboard? Again, sorry, but I'll ask a basic question because I don't know your familiarity with Kibana, but did you go into edit mode and change the size of the panels to better fit your visualization?
Because it's up to the administrator to build dashboard items, that means they have some say over the layout and which panels do or do not show scroll bars. Often, simply upping the size of a panel will remove the scroll bars.
If you're seeing issues beyond that then please place an issue on Github along with a screenshot of what you're seeing and I'll check it out.
