Please, see attachments for additional info and screen shots with artifacts.
Also I've tried the latest git drivers from here:

with the same results:

libdrm: 2.4.68+git1606070630.70b640

Please try to disable use of GL for composition if you have a compositor
enabled. The nv30 nouveau backend (which covers nv4x as well) has many
deficiencies, and I would not recommend using it for desktop composition.

[also, don't mess around with importance settings - i'm sure this issue is very
important to you, but these settings have no meaning in this project - but they
do highlight the issue as red, which is annoying to me.]

Actually the situation is slightly somewhat different. It is not possible to
work with compositor enabled because of too many artefacts appears all the
time. So this is the only way - to disable compositing - to be able to work.

>also, don't mess around with importance settings
I set it up as I take them for yourself. If it is possible to set is up for
reported then somebody decided it should be like that. You're not agree - you
changed them - it's OK. No problem. I just don't know in what project what
setting can or can't mean.

Please, ask for any additional info if needed.

Thanks.

Can you clarify whether you're seeing the artifacts without any compositor at
all, or if your compositor is using Xrender, or if it's using GL?

I can clarify that artifacts that you cat see in attached screen shots is
seeing only with OpenGL 2.0 EGL enabled. But there is another artifact I'm
seeing after some time working under XRender - it is text distortion. Please,
see attachment.
