Tooltip appearing in top left corner of browser when a field is added

Tooltips in custom visuals are appearing at the top left corner of the browser window in Power BI Online (screen position 0,0). This bug began around April 20, 2020. 


I thought this might be a bug in my custom visual or a bug caused by conflicting libraries so I tried to test using a newly created, basic visual. This bug occurs in the update counter visual that is created by default in a new visual which is attached with minor changes to show the tooltip on mouse down.


This bug appears when a field is added to a category and disappears when the visual is updated either through a selection in a different visual in the report or by changing options in the formatting pane or adding a measure. The bug reappears if the field is removed and a field is added again. In reports with multiple data roles, the issue reappears when all fields are removed from the visuals and fields are added back in again.

Any idea when the fix will be released ? I would like to demo a report which uses tooltips. 

This bug was fixed in service. ETA is June 6th, and the next version of the Desktop app.

  • We have the same problem in Report Server.

We were using Power BI Report Server (January 2020) and everything worked fine.

Recently we've updated to Power BI Report Server (May 2020).

In one of my reports I'm using Power BI Certified, Radar/Polar Chart by xViz


When I first open report in browser it works fine. But when I navigate to other pages via bookmarks and then back to the first page, the tooltip jumps to the top left corner.

Will this be fixed before the Sept release of Server version?




Thank you for noticing.

It's a known issue. Unfortunately, it's a problem in Power BI service itself, but not in some visual code.

It should be fixed soon.
