'AndroidStudio get more and more dark grey bars when opening dialogs

Text AndroidStudio(Arctic Fox | 2020.3.1) get more and more dark grey bars when opening dialogs. When I open a dialog, something wrong happened that a grey bar appears. Grey bars have no response to click. Restart AndroidStudio can work, but this bothers me when I focus on work, I have to stop working to restart it. Updating to newest version of AndroidStudio can not work. What can I do to remove all these bars?
