Hello, all. We recently-ish rolled out Zen 2017. We are having a weird issue on the workstations now. When a workstation minimizes the application launcher, the tooltip that you usually get for hovering over the minimize button remains on the screen. Occasionally, maximizing the re-minimizing the application launcher resolves the issue, but not typically. Here's a snip that I took of the issue.

Is anyone else seeing this and/or know how to deal with it?
