Lightroom 6.0 slideshow (Windows 7)- when exporting slideshow as 1080p high quality video - some of tiff images rendered as swapped blocks - i.e. bottom left 1/4 corner of the picture shown at the top left and vice versa.

This has been fixed in Lightroom 6.2, which is available today. (Actually, it turns out this was already fixed in Lightroom 6.1.1. Yeesh. I apologize for not updating this thread earlier.)

Thanks,
Ben

Thank you very much for the response, Benjamin. That make good sense to me. Now it's just a question of how soon Adobe will make the required tweak. I think many of us - myself included - are frustrated that it is taking so long for this to be addressed. Anything that Adobe can do to speed this up would be greatly appreciated. Even something such as a global switch that we could set to disable the optimizations would be great for me. Auto-detecting cards/drivers with the bug is great, but if that takes too long, I'd rather have control over the switch myself than to have to wait longer.

A performance optimization introduced in a recent Lightroom version causes this problem on certain AMD cards due to a bug in the AMD driver. We have alerted AMD to the problem with the driver, and they may or may not choose to address it. In the meantime, we intend to drop this optimization (just for the affected AMD cards) in a future version of Lightroom, so as to work around the issue with the AMD driver.

The problem is that if you go back to an earlier version of the app, the images will render perfectly - on the exact same PC. So, while it's entirely possible - maybe even probable - that the bug lies in AMD code, Adobe absolutely has the ability to work around it. They are neither providing a workaround nor any explanation regarding what the real issue is and what we can expect. Other may disagree, but I think they owe us that.

If it's an AMD bug and they Adobe has proven that, they should come out and say it and let us know how we can help apply pressure to get it resolved. If they have no intention of ever addressing it, let us know so we can each decide whether or not we want to ditch the app, swap video cards, or just live with the limitation.

Do you mean it hangs/freezes? Crashes are a very different behavior from hangs/freezes.

Adobe cannot fix bugs in drivers. And to use the GPU features, an application has to rely on the GPU driver code working correctly.

Support of Lightroom with AMD is getting ridiculous - with finger-pointing instead of problem-solving. With AMD 15.7 driver version Lightroom develop module crashes all the time and is not functional at all:

with 15.8 beta at least develop module is back to work, but no word on this issue.

Somehow much smaller game-developing companies do not have such issues all the time, while Adobe apparently does nothing to resolve this.

Hello everyone. I have since upgraded my computer. I was tired with a slower system. Now running a Core i7-6700k running at 4.7 GHz and an MSI GeForce GTX 980 with 16 GB RAM running at 3200. I just reloaded the entire slideshow at the highest resolution and everything looks perfect. Wonder if it perhaps was the AMD card that I was running previously. As daddyscholz noted, his AMD card had the same problem and the NVIDEA card worked.

Regards,

Same problem here, 5 year old Dell XPS 9000 running Win10 64 bit with AMD card that originally came with the desktop, latest driver. Luckily I came across this thread and had a NIVIDA GeForce GTX 745 laying around from an upgrade it did last weekend on my son's desktop. Installed it in my trusty old Dell XPS and all was o.k.
