PSD files don't always display in Preview?

[Foxyrick]

I've never noticed this before and I don't know if it's always been this way or if it is a new change. I have the latest 1.02 XNViewMP installed.

Some of my PSD files show correct thumbnails, but do not display in the preview pane. I just get a white rectangle of the appropriate size. Other PSD files do display in Preview as they show in the thumbnail.

I created a simple test file, a new photoshop picture with one text layer and a circle drawn around it on the background. XnViewMP shows the proper thumbnail but nothing in Preview. Screenshot attached with that thumbnail selected.

Then I flattened the image in Photoshop and saved as another PSD. XNViewMP did show that in the Preview. I copied a few existing PSD files into the folder too.

In the screenshot, the first two images in the thumbnail pane do display in Preview. The next two thumbnails give a blank Preview. The last thumbnail is the flattened image mentioned above and does show in Preview. In other folders it seems there are more that do not display in Preview, than those that do.

Note that all the files were saved with a picture visible in Photoshop itself; I don't have all the layers hidden or anything like that.

Is this expected behaviour?

• Is Use alpha channel (or Use transparent index) activated?
  

  You can deactivate Use alpha channel (Ctrl+H) In the context menu of the preview pane, but this setting doesn't stick across sessions. The bug should be fixed in v0.91, tho.

• Which version of Photoshop do you use?
• Is Maximize compatibility activated?

For reference: Display of all layers in Photoshop files (XnView Classic)

Photoshop 2020, version 21.0.3*, but I have PSD files saved with many previous versions. Maximize compatibility is disabled, but I will enable it and try testing again later today.

On the two test files (one that does not show in preview, one that does) Use Alpha Channel is greyed out and cannot be selected or deselected. Makes sense as there is no alpha channel in the image.

*Probably should update, but they always seem to break something and this version does what I need.

Could you provide samples for the developer? PSDs can be attached to posts as ZIP archive (2 MB max).

Here are the two test files. Test1 does not display in Preview, Test3 does.

Thank you, Foxyrick I've moved the topic to bug reports.

Test1 has multiple layers, you can view all of them

[Foxyrick]

Ahh... I did not know about that. Took me a minute to find where (page next/previous).

So it's working as expected and I'm just a bit slow on the uptake lol!

That does make perfect sense, compared to having to process all the layers and states and work out what Photoshop would show (practically impossible I would think, without being photoshop).

Thank you and apologies for wasting your time.

Edit: I didn't think about it because of that file showing a blank in the Preview, because there isn't a blank layer in the file. Just the background layer with the red circle, and then the text layer. I guess it's how photoshop saves it though.

Moved back to “General Support”

Any update on this?

Update:

For me both XnConvert 1.96 and XNViewMP would not show Previews on PSDs with Smart Object Layers. Installing XnShell seems to have fixed it. All my previews are back!
