P: Scroll speed on iMac Pro incredible slow

On my 10 Core iMac Pro with Vega64 and 64 GB RAM the scroll speed of latest Lightroom CC in the library is so ridiculously slow that it just can't be true.
Disable or enable hardware acceleration doesn't change anything.
It's literally unusable like this and I only got 400 images in my library.
When flicking the scroll area of my mouse it takes 1-2 seconds until it moves.
Anyone else experiencing this? How can this be true?

    Same here, not with a iMac Pro, but with a Retina 5k iMac.
    The 5k resolution seems to be the main problem here.

    Adobe - Apple Photos App is running smooth with  10-thousands of photos, so solve this issue!

    In fact, I have a MacBook Pro (15-inch, 2016) and I have the same issue. I really don't understand how can Adobe sell a product to the MacOS with such an evident issue.

    Another workaround which might be acceptable to some, is reducing resolution of the app itself. 

    Right click on Lightroom app > Get Info > Launch in low-res mode.

    On retina displays you can increase the simulated resolution via Display properties, so that it compensates for some of the resulting UI pixelization.

    please fix this!  January 2019 - we've now had issues since the iMac pro's launch over a year ago.

    As a workaround, decreasing the window width makes it bearable.

    I, too, am eagerly awaiting this bug to be addressed. Currently, Lightroom CC on iMac Pro is unusable due to the delayed scrolling and severe interface lag. I'm having to do everything in Lightroom CC on iPad Pro as a result.

    This seems to be the case across all 5K iMacs, not just iMac Pro. Any updates? Thanks

    as told, 5K resolution, everything synced to local SSD
    10.14.1 and Lightroom CC 2.0.2 doesn't change a thing

    Same here - very disappointed. My old 2010 MacPro is faster - yeaahh. Where is the quality control for this software? Hope a fix soon.
