I was having screen tearing problems running this on a full raspbian buster img so I tried,
4.12.3.GIT
Raspbian lite + openbox + lightdm + pcmanfm.
Pi 4b 4Gig ram.
Seems to run smooth as hot butter with full a window manager and Fixture Monitor. Sweet!
Hope you stay well Massimo!

After more experimenting I have found that the compositor is causing the screen tearing and slows down qlc quite a bit.
Compositor does vsync and other windows effects like shadows and transparency.
On Raspbian Buster I disabled the Compositor in raspi-config > Advanced Options > A9 Compositor
Windows look flat and boring but the screen tearing in qlc is gone.
Same with Openbox. As soon as I installed the compton Compositor the slowdown and screen teraing began.
RPi4b 4GB
QLC 4.12.3 GIT

Hi! Sorry for bumping a old thread but I'm also interested in running X on Massimo's img. Can you explain me in detail what have you achieved and how did you succesfully run a display server on his distro?

I think it's easier to download a vanilla RaspiOS image with X and install the QLC+ deb package I provide
