Lightroom Classic: Very slow rendering in Develop module

There have been some other Wacom-specific bugs and I'm trying to figure out the links. It would be really helpful to know whether you see the same problems with a normal mouse/trackpad, and if not, which Wacom Driver you're using. I suspect that's key.

Yes, I do use Wacom tablet. Why?

You don't happen to use a Wacom tablet, do you?

LR5 is the go to app. The LR CC simply adds nothing but frustration with the crop tool unstable and many other glitches. I have decided to cancel the contract and await an update asap.

I have been using LR for years. LR CC is by far the slowest working release. The program often hangs. Also, when LR is opened, the temperature of CPUs go to max. even without doing anything. It is stressing my machine to the core.

Windows 8.1 / latest LR CC.

I'm glad I found this post and found it isn't just my MacBook! It has been getting worse and worse, to the point I cannot finish editing my season's photos and I'm getting very upset!

Totally agree - should never have upgraded to this version om LR. Have had Adobe-tech looking at my computer three times - with no success at at all. First it wouldn't import video-files, then it wouldn't import at all - for no reason it imports pictures now - but is like 15 seconds to load each picture even in loupe-mode. Even though the files just has been loaded once. Adobe-tech told me I could open the CC-catalogue in LR 5 and keep on working in that version. Not true. Lots of other glitches too.
Really hope Adobe will work fast, for once, on an upgrade.

LR6 is unusable..worst release by Adobe in a long time.

Have to agree with Laurence; LR6 is looking more like a 'train-wreck' each week.
I accept that all software has some bugs but there are far too many problems appearing in LR to be acceptable.

LR 6 CC is installed on 2014 Mac Pro 12 Core Dual AMD Fire Pro 700, 32 GB Ram 1TB SSD, Dual Apple HD 30 Displays

When I first open LR CC, all is ok, tools are fast , Radil Filter is fast, after a short time in Develop module, the program starts to slow

The Radial, and Clone tools become VERY unresponsive, as well as global adjustment tools also slow,

After 1hour when using the Develop Module, the radial filter become UNSTABLE, the filter was VERY unresponsvive,then it would cause the entire screen to go Black, no image displayed, then the radial filter disappeared, and was not on the image.

As far as I am concerned LR CC IS NOT useable, I am amazed at how this product has been released, I also run Perfect Photo Suite 8.5, and DXO Optics Pro 10, both are VERY fast and stable.

QUESTION: will I need to wait until LR 7 next year, or can they fix this with LR 6 updates,
