Portrait and landscape preview

[Alnitak-NT]

Hi,

I have a problem when I check my images on the library module. When I switch from a landscape orientation to a portrait one, I see all two photos instead of the gray background.

Is there any option to see only gray background both on landscape and portrait photos?

thanks

What version of Lightroom are you using? I know there was a bug, but it should have solved.

Hi Johan

I have Lightroom 7.2 on Windows 8.1

That should be the last version, as far I know.

I think you are alright when you say it was a bug because I remember that during last year I saw a correct preview image

PS: have you some link explaining that particolar bug?

thanks

There was a bug report in feedback.photoshop.com, probably about a year ago or so. I can't give you a link.

[Alnitak-NT]

ok, thanks!

In the LR Preferences dialog on the Performance tab turn off the option it use the GPU and then test.

Worth trying, of course, but as this is a Library module issue and not a Develop module issue, it probably won't solve it.

That has changed in LR 7.2.  The "Use Graphics Processor" option now also controls the use of other forms of accelerated graphics in Library and perhaps other modules.  See Adobe employee Simon Chen's reply here:

Lightroom: Overlapping display of images in Library | Photoshop Family Customer Community

Prior to 7.2, users could set obscure options in Config.lua for disabling LR's use of the Windows Direct2D interface, which worked around bugs with overlapping display of thumbnails and the filmstrip in Library.  According to Simon, that is now controlled by Use Graphics Processor.  There have been a number of reports of Library and Map module problems now being worked around by disabling the GPU.

So it seems that unchecking Use Graphics Processor should be one of the magic spells sprinkled on any problems with display, in any LR module. (Verifying you have the most recent graphics driver from the manufacturer is another necessary magic spell.)

Right! That was the bug report I was thinking about. Because it was older, the solution wasn't the GPU settings at that time. This makes it a lot easier. I had not seen that last reply.

It works,thanks!
