Graphics hardware in use

Quite often

Bug description

When I move my mouse onto one of the icons I have pinned to the Panel, the label of that icon is displayed--as it normally should be. Then when I click said icon and move the mouse away, the label remains. This gets in the way of seeing all the icons on the Panel.

Steps to reproduce

Move mouse over one of the icons pinned to Panel
Click said icon
Move mouse to new window

Expected behavior

The icon's label should disappear after moving the mouse away.

Additional information

This happens with certain icons/apps: shells such as Bash, Midnight Commander (under bash), File Commander, Mullvad Browser, and app called Local Send (on Github).
