Isolate those corners and check again.
Actually, it's not just vignetting. When the house and the roof of the shed get brighter, the brown foliage gets darker.

I checked this on PL5 too, but on the new system only. And did not noticed this bug earlier (playing with photography occasionally, if truth to be told) on any of PL versions. The bug became visible with particular set of images, that required quite a lot of adjustments involving high clearview settings.Did you not see my screen shot? Here it is again:
We already know that two other experienced PhotoLab users here have said they can't duplicate the issue. This behavior (on my system) is seen in PL5, which was released two years ago. If something this obvious is widespread among all users, we should have seen other reports before now.
On my newer system bug "works" with and without GPU enabled. I did not checked it on the older system.

This procedure is reproducible on my images. The whole image turns "bluer" when the local adjustment is visible.

I also submitted a support request to DxO.

One more example.
Here is test image:
And here are applied modifications. Last image shows local settings:
Three above images are the images with local adjustments enabled. Local selection is done with a simple brush.
And here it is how it looks with local adjustments off:
Anyone can download source image (the first image from the series) and try to replicate bug. It "works" with jpg too.

I can't wait to hear their responses. Hopefully you'll have better luck.This procedure is reproducible on my images. The whole image turns "bluer" when the local adjustment is visible.

Yes, agreed. I've done another test, with a stronger LA effect, and I can see that the effect, though slight, does affect brighter areas across the image.
LA off
Stronger LA on. The brightness of all other bright areas is reduced very slightly.

You have repeatedly avoided complying with my simple request. Why?

So it's fair to say that some anomaly does exist with your system, although it's much less apparent than it is with mine.
I know you normally use a custom preset. Maybe you can try with the No Correction preset applied just to limit any other variables.

Thanks, that's a pretty significant change. Up until now, you and Digital Nigel were reporting no issues. I guess this is a better test.
Can you check by looking here to see if your GPU is fully or only partially supported?

Sorry, I did not get it. I'm not a native speaker
Here You are:
When I point at the exclamation mark it shows following:
Displayed statement is not correct.
I hope this is what You have asked for (I have PL6) ?

The effect depends in some way on the content of the image. This may be because the depth of the Clearview effect depends on certain image characteristics.
At the end of the thread I posted another test (link: https://www.dpreview.com/forums/post/67339176) with downloadable "synthetic" image. Only a few settings are used, so they are easy to reproduce. Maybe it is worth to check it in Your system?

You will only see that warning in that particular place ... and you will only see the asterisk next to your GPU if it is not fully supported. I know this is in regard to DeepPRIME, but it still could indicate that 'errors' might result in other features.

Lol, I've edited my post while You have answered it, so You did not noticed this image (which now is in place):

I've tried it, and the effect is the same.
Reducing the opacity of the local adjustment reduces the effect, which is probably why most people don't see it — I would never use such an extreme local adjustment. At the normal levels I use, the effect is too small to be seen, or to matter.

Thank you. Then it appears that the effect can be fairly easily seen on some systems even if the GPU is fully supported.Lol, I've edited my post while You have answered it, so You did not noticed this image (which now is in place):

After some more experiments, I think I've pinned it down to how ClearView works.
It seems to do some sort of averaging across the image to produce a balanced effect. So, if you have a large local adjustment that does dramatic things in part of the image, CV adjusts the rest of the image to balance it (so a very bright LA area causes a slight darkening in the rest of the image). This applies even if the CVP is applied via another local adjustment rather than globally.
If CVP is used at typical levels (ie, much less than 100), the effect is too mild to be noticeable.
What isn't clear is whether this is a carefully designed effect that's been deliberately programmed into the ClearView algorithm, or a bug.

The other part that isn't clear is why some systems show a very distinct difference while in others the difference is barely perceptible. Or is that a consequence of the content of the image? So far, I don't remember any of us running the same tests using the same source image on our own systems.

Yes, that's why I asked the OP to share a raw+dop file to try on other machines, but he refused. I'm now coming to suspect that computer hardware or PL version or camera model isn't a factor: it's just how CVP works, probably by design, but perhaps accidentally.

It doesn't have to be RAW, does it? Let's try a DPR source image.
DPR source image
Apply these settings:
- DxO Preset: No correction
- Color Space: Wide Gamut with Generic Rendering (should be the default with v6/ v7)
- Global CVP: +100
- Local adjustment brush with Exposure set to +4.00
Brush selection enabled
Brush selection disabled
