Image zooming/viewing does not work properly on MacOS

Using a supported version?

Overall summary

When clicking on an image to zoom it in, the size of the image preview is tiny within the overall window, and clicking to zoom in on the image does not view the image at full resolution. Additionally, the image should open in a pop out separate window.

Steps to reproduce

1. Go to any chat with an image. 2. Click on it, observe small image. 3. Click again to attempt to zoom in, observe that the zoomed image isn't full resolution. 4. Additionally, stretch the window size and observe that somehow the full resolution zoomed image changes size as the window changes sizes

Observe large black area around image after clicking on it, showing that clicking it doesn't do much:

Observe that even when zooming it only zooms partially and maintains a large black border:

Observe that changing the window size changes the zoomed resolution:

Thanks for your feedback. This is not a bug, as it's by design. The screenshots suggest a window size which is very wide with low height, and we don't support this size well currently. This could be considered a UI enhancement type of issue. As for not popping out the image in a separate window, this is intentional.

For feature/design related enhancements, it is more helpful to share it in the forum where we will prioritize based on feedback. https://community.signalusers.org/c/feature-requests/desktop-feature-requests/20

@ayumi-signal This behavior changed recently. It didn't used to work like this. This is a bug, not an enhancement, please re-open. Also the natural way to use signal is a wider than tall window, because of the contacts list on the left side.

[mlindner]

Also you're missing the fact that image zoom does not work properly. It used to show the full image resolution, but no longer does that.

If it's the case that this is a regression, then I apologize. Can you provide the app version # where zooming was working as expected?

[mlindner]

I did some looking back at versions and the size of the black border size greatly expanded at least between 6.43.1 and 7.0.0. It's hard to test because of the database changes. The same image has a much larger black border after zooming in 7.0.0.

[mlindner]

It seems 6.43.1 still has the zoom not being full resolution, but the problem seems to not be as bad as it is in 7.0.0 and later which is perhaps what caused me to notice it.

Thank you for the additional information. We will take a look.

@ayumi-signal I'll add it has nothing to do with wide window aspect ratio. Making the window very thin and vertical shows the same issue.
