Hello, there is a visual bug on JiraWeb when we try to change the status of a task. The popup displays on the top left corner.
You'll need to show us the problem, and explain when it happens. Have you tried another browser?
I had the bug on Google Chrome. I just tried the same in Safari and I still have the bug.When I click on a task status to change it, the popup displays on top left corner as you can see.
