P: slideshow - images rendered as swapped blocks

same issue, same optical result of corrupted slides in a slideshow. I also do have a Radeon graphics card (5700). This one I downgraded the driver to make use of the GPU (which otherwise was not identified by Lightroom.

Am not sure if relevant but I am running two monitors from my AMD HD6670 card. I did try exporting slideshow with 2nd monitor turned off but got same swapped block issue and again 3 times at least slower to export the slideshow in 1080 - I noticed that 1080 is now called 16:9 in brackets - is this significant?

Haven't tried to unplug the the 2nd. Monitor from card yet but may try at some point. For now I am exporting the slideshow as a catalogue and opening it in LR5 so I can export it as a 1080 slideshow in the older version that works!

Same issues I already posted a thread on this when I discovered day 1 of the new LR CC being launched. Glad to know it's not my Set up and others are experiencing the same issues.

Thank you so much! I have downloaded those tiff files. I will keep you posted on the progress.

Hi, Please, see link below - contains 3 files and slideshow generated from them.
Let me know if anything else is needed

Would it be possible that any of you upload some test image files so that I could figure out that problem?

On the same machine I had the problem, I disabled my GPU card and switched to the chipset's Intel HD 4000 instead, just with lower resolution (as I need the card for high res dual monitors), and the slideshow worked fine. So it seems it is the combination of v6 and the graphics card. The slideshow also took about 3x as long to produce as LR 5.x. All of this combined resulted in me switching back to 5.x rather than spending $300 for a new card white-listed by Adobe, when the card that I have has more than enough horsepower for simple image editing tasks.

I also tried the latest beta graphics drivers from AMD so the fix isn't even in the pipeline.

Hi, Chris, do you have any other suggestion, that would work?
