Installing on newest raspian-stretch-lite fail

I installed nanoDlp on the newest raspian-stretch-lite.
Starting fails with the error

"./printer: error while loading shared libraries: libGLESv2.so: cannot open shared object file: No such file or directory".

Then i installed ligbles with
"sudo apt-get install libgles2-mesa"
"sudo ldconfig"

pi@raspberrypi:~ $ ldconfig -p | grep libGLESv2
libGLESv2.so.2 (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2

but error persist.

Re: Installing on newest raspian-stretch-lite fail

Have you tried upgrading firmware? sudo rpi-update
I am upgrading to latest OS to see what is the issue. But I remember that I have encounter this before

A rpi-update actually helped.
Now it works.
Thank you

Re: Installing on newest raspian-stretch-lite fail

Can I somehow install NanoDLP on the official Raspian Stretch version without rpi-update?
With "rpi-update" I get Raspian 9 (stretch) Kernel 4.19.34-v7 +
But then the display flickers.
Maybe this will give me an immature beta version.

On my old system I had Raspian 8 (Jessie) Kernel 4.1.19-v7 +
and I could not watch that.

==========================
2K LCD display, 2560 x 1600, 8.9 "
Raspberry 2B + (I also tried 3B)
NanoDLP 2175 (and also 2177)
Enough power on both the Raspberry and MIPI board

What really confuses me is that when I change the resolution to HD, the picture does not flicker.

if I regenerate the plate, then I get this (only my hand is moving a bit)

then change the setting

regenerate the plate, then the image flicker

both with (rpi-update)  Raspian 9 (stretch) Kernel 4.19.34-v7 +

Check config.txt I guess something is wrong there which cause issue on the latest firmware.
