White screen with mouse cursor

[BKeyport]

MagicMirror 2.11 bug

Platform: Raspbian GNU/Linux 10 (buster) on a Pi 4 using HDMI0 output. Node Version: 10.15.2

Description: White screen with mouse cursor for 2-5 seconds before magicmirror continues to load, then mirror loads normally.

Steps to Reproduce: Start Magicmirror (I use PM2 to launch mm.sh - which is)

cd ~/MagicMirror
DISPLAY=:0 npm start

Expected Results: clearing of GUI to black screen, with MagicMirror starting right away.

Actual Results: See Description

Configuration:
