I think the original 1013 had flicker and tearing before the screen went blank
(the os was still functional - ssh worked).
With your image/modules/buildinfo i get:
uname -a
Linux ubuntu 5.3.0-1013-raspi2 #15+v3d SMP Sun Nov 24 13:41:44 CST 2019 aarch64 aarch64 aarch64 GNU/Linux
Enlarging the glxgears window: I see flicker between the glxgears window, the background and terminal window when they overlap instead of just seeing the top one.
It hasn't gone blank ... yet

With pi 4.19 kernel/modules (from https:/ /github. com/raspberrypi /linux) there is no flicker and the screen has never gone blank.
