Lightroom: Slideshow background image displays poorly (low resolution) in Preview and Play

[Bob_Benedict1]

Problem:

I have selected a
background image for the backdrop of my slideshow. It appears sharp with a high
resolution appearance in the Slideshow Module work space. When I switch to
[Preview] mode or [Play] mode the background image quality degrades
significantly. The slideshow images remain sharp. An old slideshow that worked
perfectly with LR4 has the same issue under LR CC.



Attempted Solutions:

I have selected different
Quality settings for Playback. I have tried multiple images with various
resolutions for the background. Toggled  [Use graphics processor] in preferences. Restarted LR & Windows. Searched for
solutions online.

Others have reproduced this issue and also reported color management problems with the background image as well.

I just tested this on Windows 7 using CC 2015.8 with Canon 5D MKII raw files. The Background image is still soft and exhibits "jaggies."

In addition the selected Background image file's Library preview is corrupted and displays as an sRGB image in the ProPhoto RGB color space. Here's an example showing the Background image file's Library Preview Before and After running a slideshow:

Hi Robert,

This should be fixed in the CC2015.8/6.8 Update. Give it a try and let us know. 

Thanks,
Adobe Lightroom Team

[Bob_Benedict1]

FYI: The issue has NOT been fixed in the latest release CC 2015.6 [ 1078672 ].

I can confirm the behavior and have filed a bug. 

[Todd Shaner]

Rikk, in addition to what has already been mentioned the background image is not properly color-managed when viewed in the Slideshow normal Loupe view. On my wide gamut monitor reds are oversaturated. The actual Slideshow JPEG, PDF and Video output files display the background image properly so it's strictly an issue with the onscreen image inside the Slideshow module.

This problem is present in the latest LR CC 2015.5.1

[Rikk Flohr: Photography]

Your first step would be to update your Lightroom to the current version 6.5.1 and see if the problem persists. There have been bug fixes since your 6.1 version was released.

Thanks for the info Todd. I will try to do that.

[Todd Shaner]

One thing I forgot to mention is that I'm using a wide gamut monitor (NEC PA272w). Try it on a system with a wide gamut Adobe RGB display.

[Smit K]

Hi Todd,

Thanks a lot for sharing the info.

I was able to reproduce the background image not displaying properly issue but not the Color space change issue. Let me know if you are able to reproduce the issue about the color space change with some other image as well.

I have updated the original bug with the info.

Thanks,
Smit

Smit, I updated my Nvidia Quadro graphics driver to the latest 375.86 ODE drivers with no change observed. I also checked Windows 7 Update and there were no new updates. I've emailed you the catalog share link. Let me know if you need anything else.

[Smit K]

Hi Todd,

Could you create a collection with only this background image. Export the collection as a catalog and share with me.

You can email me the link at keniya@adobe.com.

Also, could you check if there are any updates pending on Windows as well as if the Display Drivers are up to date? Even if you have turned off the GPU setting in the preferences, library used in Slideshow requires GPU and outdated Display Drivers could create issues here.

Thanks,
Smit Keniya

Update. The bug still exists in LR Classic CC 7.5 (8/24/2018)

[Bob_Benedict1]

I have tested the slideshow background issue in CC 2015.8 (had unrelated issues updating to the new release). There is no change in behavior. Background image still degrades in Preview or Play modes. Windows is up to date.

Correct. This thread is still marked "In Progress" and the bug is still open. 

[Bob_Benedict1]

FYI: As of Lightroom version: CC 2015.10 [ 1111918 ] the issue has not been fixed.

[Bob_Benedict1]

FYI: As of Lightroom version: CC 2015.7 [ 1090788 ] the issue has not been fixed.

[Todd Shaner]

Thanks Rikk.

[Rikk Flohr: Photography]

My Apologies, Robert. I read from the line below as 6.1. I see that you are on 2015.5.1.

[Bob_Benedict1]

As I listed above in system info I am using 2015.5.1 [ 1073342 ]

[Rikk Flohr: Photography]

Thank you for confirming Jao.  I will try and duplicate.
