First of all @flyingpauls - this has absolutely nothing to do with what you are talking about.  You are completely misinterpreting the situation as other have said.  I have flown some complex areas, and I haven't seen this.  If anything countryside areas seem to be affected more.  It is localised, but does seem to be spreading.  If you watch the video posted earlier, do you actually think this disappearing landscape is a 'feature'?

Also, I first saw this problem absolutely ages ago, maybe 18 months or more, off the end of the runway at St. Barts.  The water masks convert to solid blue in a radius around the aircraft, and then reappear again at a distance, just like shown in the video.  I have actually seen the St. Barts issue on somebody else's YouTube exactly the same.

Anyway, there is a sizable thread at the official forums now, with plenty of evidence.  'Bug Logged', but not much else in terms of feedback yet.

I would clearly separate texture popping from mountain morphing. The latter has been with us from the start of MSFS. It's still there, but partially improved on e.g. during world updates. It can be characterized as mountains springing into shape when you approach, but textures themselves are not exchanged as such.

Texture popping is a new effect and, as far as I read and can confirm from my own experience, appeared first a few weeks ago. In this case, tiles of texture are replaced by new tiles while the ground shape itself doesn't change.

Kind regards, Michael

It's been around for ages, I saw it very badly when the UK & Ireland World Update was released over two years ago.

This is interesting. Maybe it appeared in rare places earlier and I might have forgotten it as a one-off phenomenon? In any case, it seems to spread into numerous regions right now.

Kind regards, Michael

I first noticed it in the France update, and it’s still particularly frequent in France.

I’d be curious to know what it’s updating with. Do they have two sets of tiles for the world?

I just tried Snowdonia - the mountain range in North Wales in the UK:

This is where the famous 'Mach Loop' is flown

Not quite right. The Mach Loop circuit is further south in mid Wales. This site shows the location. https://machloop.co.uk/finding-mach-loop/

There are places where it is new and places where it has been here for quite awhile. Also, in some places, it is barely noticeable, specially when you are busy managing  a takeoff or a landing, some others where it is horrible. 

About mesh morphing/texture popping. The latter often accompanies the former. But you can get popping without morphing.Two different flaws indeed.

Yes, I don't think the guardians of Eryri (the traditional Welsh name with which Snowdonia has been 'rebranded') would take too kindly to Mach Loop antics there!🤭

Quite right!  My mistake - thanks for the correction 🙂

Yes - good observation and worth separating the two aberrations.  But in that Snowdonia region, I reckon there's a bit (lot) of both.  In the medium distance, there are definitely features where the shape suddenly changes or a feature, such as a scree bank, appears.  And yes, 'twas ever thus.

But close and slow, there is most definitely what I would call texture change all over the place.  I'll try to get some 2D video to illustrate.

I've seen this so called texture popping  (I'd prefer to describe it as texture swapping) while flying in non photogrammetry areas around the lower Fraser Valley in BC for probably over a year now. It only seems to occur at low altitudes (500 ft agl or lower). It is not that noticable during most flights, but it can break the immersion during low flight and approaching to land.

Yes - that's a great way of describing it.

I'm presuming that it is linked with the immense challenge of having a full 3D rendering, on a moving viewpoint and lighting, of an undulating surface...

This texture swapping is a very real bug and it’s in various places.

ifvyou want to see it in action you’ll see it in these places for definite.

monterrey Mexico and south of the city

malta

Nice

monterrey and Malta are pretty full in whilst nice is a lot more subtle. It also happens in Hawaii slightly north of the navy harbour. But it’s incredibly subtle.

When I experienced this over southern Italy,I was not at low altitude at all. I was cruising along at FL370 or so and it was very prominent every time I looked out the left window from the cockpit. You are right in calling it texture swapping though, as that is how I would term it as well. It is extrememly bothersome and absolutely kills the immersion when it happens. 

All that said, I have NOT experienced it since I deleted my DirectX and OpenGL shaders the other day. I have only performed a handful of flights since then, so I cannot say that is a definitive fix on my end yet. But, so far so good.

You can see the textures moving/swapping on the mountainside rock and grassy outcrops to the right of the cockpit in this short video here.  Snowdonia, Tiger Moth, HP Reverb G2 captured with the Windows 10 Game Bar facility at 60fps:
