Image always briefly blurred when editing
With the latest C1 Version (16.5.2.2623 on Windows 11) the image in the viewer is briefly blurred each time it is edited.
You can see the effect most clearly when you zoom in: The image remains slightly blurred until the calculation of the new value is complete. Then it is back to its usual sharpness. This change is very irritating, especially when working with speed edit.
I'm not sure if it was due to the last update or if version 16 has always done this. Older versions (version 14) do not show this behavior. I think it has something to do with the new preview calculation in version 16.
Has anyone else observed the same behavior?

- It is worth checking that your preview size is set to an appropriate amount for your monitor. (See screenshot below.)
- You can also check what your other settings are for previews - see this section in Capture One settings.
You could experiment with changing all of the settings I have highlighted, and see what gives the best result on your system. (But I don't recommend changing the preview image size to anything other than the recommended setting for your monitor.)
- When you zoom in, Capture One has to access the original raw file. Are your raw files on an internal drive or an external one? Is accessing them a speed bottle-neck if they are on an external drive?

Thanks for your answer Ian.
I have experimented with the settings, but it does not seem to be due to the speed.
If you continuously zoom into the image (with the mouse wheel), the preview always remains sharp.
If you make a continuous change instead, for example the exposure with speed edit, you can see how a veil is briefly placed over the image until the calculation of the value is complete.The calculation of the value is actually quick (I actually have no reason to complain about the speed of the calculation), but it is only because the images keep changing that you notice it. Depending on the object, this quickly changes becomes irritating.

The other thing you could experiment with is the hardware acceleration setting in the General tab of Capture One settings. Does that make any difference?

Not really. If I switch the acceleration to never, you can observe the effect a little better, as the calculation now takes a little longer.
Doesn't it show up for you? (best see, if you you zoom to 100% with a sharp edge or object and then make a speed edit).

See this image. (Zoomed to 100%, then the screenshot reduced in size to fit in with the 2MB limit for images in posts.)
If I use Speed Edit (for instance to adjust exposure) I see this.
- The brightness of the image increases continuously as I scroll, but
- The sharpness does blur (for less than a second, I think) - particularly noticeable in the feathers under the heron's bill.
So I see the loss of sharpness very briefly, but I couldn't honestly say that it is long enough to bother me or slow up my workflow. I can certainly judge when I have adjusted the exposure to my satisfaction, whether or not the sharpness is impaired while I do it. It might be more of an annoyance if I were adjusting something like sharpening or Structure. Whether it has always done this, I can't remember. I suppose that as it is zoomed in to 100% it has to recalculate the preview it is displaying as you adjust things.
I've tried changing the preview settings both between the speed and quality trade-off, and with the option to use the legacy preview format (regenerating the preview each time) and I can't see a difference in the speed of this effect.
My MacBook is now 4 years old, so it is fairly behind the times as far as speed is concerned. (In other contexts this is very noticeable - the new Photoshop feature of removing reflections happens very quickly in demos online, and takes forever when I try it, and then doesn't always work.) So it's possible that it would be different on a newer faster machine.
How long does "briefly blurred" mean in your case?

Thanks for your testing Ian. (it's funny, I used a similar gray heron picture for testing).
The duration should be just as short with my computer as with your setup. I agree with you that it's not necessarily long enough to bother me or slow down my workflow.
What is annoying, however, is the rapid change of the image between blurred and sharp when you are looking for a setting by continuously changing the values. If you try to concentrate on a certain part of the picture in order to capture the change exactly, it becomes difficult if this part is always changing. That's how I first noticed it.
