Please turn off the Graphics processor from the Lightroom preferences.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Let us know if that helps.
Thanks for the tip, but it did not solve the problem. The Graphics Processor box was already unchecked. On a hunch, I tried it both ways, checked and unchecked, but it didn't work. The problem with straightening assembled panos was that use of the auto, vertical, etc was that they would produce distortions similar to that of the Full button when it has something in the frame that is a lot closer than the rest of the photo. Sometimes the auto, vertical, level, and full button images would freeze, becoming unresponsive; or display only one panel of a previously assembled pano. I tested the functions on panos from an earlier date; no problem. I could not duplicate the problem with panos taken at a later date; but panos as of 4-6-2016 still react adversely to straightening with the Upright function. They are landscape shots of a bend in a river; a site that I have shot numerous times without problems with the Upright. Hopefuly, the problem is confined to a single shoot, and is just an odd anomaly. Thanks for your quick response.
I've noticed this for a few months. I do real estate photography and before the auto function would work about 90% of the time. Something changed and now the program never gets the verticals correct. Even when there are very obvious vertical lines, it's usually off. This feature used to be tons more accurate. Now it's a chore having to manually adjust things.
EDIT: I created a thread months ago about this problem. Adobe has yet to address it.
Well guess what? I started having the same problem this morning. But it was in Photoshop CC after having exported of .nef file from LightRoom CC to Photoshop CC for some work. After having returned the file to LightRoom from Photoshop, the problem disappeared. I had this problem a couple of years ago, but it seemed to correct itself and went away.
Thanks for the info. I've noticed what you describe. Previously, Upright Auto worked well most of the time, but now it seems a little off. I wonder if the most recent update did anything to the lens profiles. Maybe the Upright"s bad pano behavior is just an extension of its missing the mark on single frames? Thanks again.
Thanks for the info; maybe it's not just my pc after all. I have a stand alone Lightroom 6, but no Photoshop to export to. I hope Adobe can tweak things to ge Upright back up to snuff.
It's not your computer, it's the Lightroom software. I bet I could put a picture with 2 vertical lines into Lightroom and it still wouldn't get the verticals correct.
Thanks for the confirmation. For now, I'll just struggle through with manual adjustments, and hope that 6.6 or 7.0 will be better.
