I can experiment, thanks.

sure. so are you using the intel or the nvidia for display ... for rendering?
sometimes they are used separately.

basically the nvidia driver does have a bug. if you go to:

settings->look->compositor->advanced->rendering

and at the bottom change swapping method from "auto" to "invalidate" does
flickering go away? if not then it may simply be an artefact of your display
panel  the good old interlaced display kind of flicker... but i'd find this
odd... i'd have to see it myself to know.

and they don't support partial buffer updates with buffer age - we do. we use
advanced features drivers offer. it happens to work amazingly well on other
drivers (mali, even rpi's vc4), but nvidia seems to have glitches where it
starts reporting incorrect buffer age... the automatic vs invalidate above
forces evas to cease listening to the driver and what it reports and just
ignore it (which is almost certainly what everyone else does as they likely
dont even have the support).

 To check for GPU, run the command: lspci | grep VGA

 To check the video driver, run the command: glxinfo | grep "OpenGL version"

 I'm using an Nvidia 670MX, with driver 367.57.  I don't get any rippling.

 The more recent Enlightenment WMs are quite different to E17.  Specifically,
compositing is now permanently on, which makes it more demanding on your
video driver than XFCE (Xubuntu uses XFCE for a Window Manager).  Assuming
you're using OpenGL for compositing.  You can always switch to software
(in Settings->Look->Compositor) if you're having driver difficulties.

Because I have never needed to ask or specify — my requirements are more
for cpu and memory than for graphics. I checked: it's a Dell XPS 8900.

I am aware that nvidia graphics drivers cause problems — I've seen
comments and complaints about them for years — but I have never
experienced problems, so maybe I have just managed to avoid them.

I looked up my specification, which says:

Right. But the problem I described [above] ONLY occurs when using the
new Enlightenment I compiled last week. It does not occur when using the
xfce or xubuntu display managers, and it did not occur when I was using
the repo-supplied e17 Ubuntu package. As I said, it's minimal.

maybe? how do you not know what gpu you have or that is being used? if it's
nvidia and you're using nvidia drivers it's a whole buhahah to get the
proprietary drivers installed + working in addition to or as a replacemenet of
mesa... if tis a modern-ish nvidia gpu nouveau (mesa) won't even work...

this matters. so know. because nvidia drivers seem to have a bug with buffer
age support. it's specific to their drivers. there's a work around to disable
partial render but knowing your driver is important... :/

On one machine (only) running my new e, the URL bar and bookmarks bar

I am not to sure of what you are describing as there is no animation
in the default background. Still I had in the past a very bad screen
on one of my laptop that would kind of look flickering on the default
background. I switched the background to a different image (The system
Light background provided in default Enlightenment installation) and
it fixed the problem.

[e-users] background rippling

Hi All,

I just installed e on a new work box, and the background is doing this
wavy-like rippling thing that's making me dizzy. How can I make it stop?
