First, I’m an Avast user and not an Avast Team member.
Others are reporting similar occurrences but not in the volume you are stating, looking in the Avast Antivirus section of the forum.
Can you give some details on what is being displayed, e.g. just UI or a specific part of the UI.
You can capture a screenshot, save it to your local drive and use file explorer or other similar program and drag and drop the image into your post.
