Description Paul Cercueil 2020-01-13 18:16:13 UTC 
From the patch:

"When the video subsystem is initialized, the framebuffer might not be in
the video mode that the application targets. In that case, if we don't
clear the framebuffer, for a short moment the display will show the
previous image distorded by the mode change."
