Can you try the regular xcb qpa plugin and see whether that has the same
behavior?
UPD: Now, I have running the qopenglwindow example application with
QT_QPA_EGLFS_FORCE888=1 and see that flickering artifacts occurred
sometimes.
It is an interest moment, that without QT_QPA_EGLFS_FORCE888, the OpenGL
draws the rectangle more slowly.

I haven't found an example which works with the OpenGL ES2. I have tried
"hellogles3" application, but it failed too.
UPD: When I use RGBA in QML, then I see following debug messages:

see only a black screen, and some of OpenGL textures errors.

I suggested to use an OpenGL example, not a Qt Quick one. We're trying to
isolate where the issue is in the stack. So use a single threaded, plain
OpenGL application with a 32 bit framebuffer and see if that gives the same
issue.
Cheers,

So, I have compiled the standard Samehame QMML application from:
/home/builder/Projects/qt5/qtdeclarative/examples/quick/demos/samegame/
and got same artifacts when I use RDBA= mode.
I have "screenshoot" of this flicking attifact:

You may need to modify it to explicitly request R8G8B8A8 using a

Do you mean: I should take any OpenGL application from the Qt examples? And
to check there?

Hi,
Can you try a plain OpenGL test application with RGBA8 framebuffer and see if
that exhibits the same flashing/flickering problem. If so, it's a
driver/hardware issue.
If you are forced into then using a 16-bit framebuffer, then you can avoid the
banding by using dithering in your gradients
